BMW Performance Headers & Downpipes

These N55 downpipes feature larger piping and catalytic converter that are freer-flowing than the original cats for better flow and less backpressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.

Features:

• 200cpi Catalytic Converter
• 100% perfect fit - CAD designed.
• less thermal load on the turbocharger
• more power by reducing back pressure
• significantly more torque
• Made from 1.4301 (SS304) Stainless Steel

For 2011 models, pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one..

These Supersprint 'Sport' headers for the Z4 M are a replacement for the stock manifolds/cats. These are the tubular 'linear' equal length headers (not the racing stepped headers) that can bolt to the stock Euro section 1 of the exhaust or a Supersprint Euro section 1. For making S54 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears). Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and de-forming (any headers not made from stainless suffer from structural problems). Supersprint designs their headers with CAD programs and 50 years of exhaust tuning experience. These headers are an improvement over any 'Euro style' header on the market. This part is designed for the US market with the correct flanges for the US exhaust and the O2 and EGT sensor ports pre-installed. Special software or stand alone engine management would be required to keep check engine and fault codes from appearing. Software is recommended to maximize the performance gains from this header upgrade.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

These Supersprint 'Sport' headers for the S54 are an upgrade to the factory Euro headers, producing more power and torque while being a straight bolt-on to the rest of the factory exhaust system. These are the tubular 'linear' equal length headers (not the full racing stepped headers) that can bolt to any section 1 - US, Euro, or a Supersprint Euro section 1. And these headers are constructed with all of the O2 sensor and EGT sensor bungs for a US E46 M3. For making S54 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears). Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains.

Sound + Power + Quality = the ultimate exhaust upgrade for the E46 M3. The Supersprint Race exhaust has a lot of fans, us included, with the mufflers producing an intoxicating shriek. This system covers the entire E46 M3 exhaust - headers, section 1, section 2, and rear mufflers with special discounted pricing. Although sound is subjective we feel the full Supersprint system produces the sexiest, most thrilling exhaust sound. It's an exotic, European-type sound unlike most American-made rumbling exhausts and it blends perfectly with the technical sophistication present throughout the E46 M3. This system does not diminsh the rasp inherent to the S54 but it's a refined and tuned sound that has won over many fans. And it's not all about the sound - the catless stepped headers free the engine of 30+hp. It's the first system we think of when customers ask for the best. Full system details:

• Stepped Headers - replaces factory manifolds and cats; equal length stainless tube in increasing stepped sizing
• Section 1 - matching stepped sizing straight pipes or metallic catalytic converters
• Section 2 - with or without resonator cross-over pipe
• Mufflers - Lightweight Race mufflers
  
• Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation! 

These are the left and right manifolds for your BMW 8-Series.

Headers, Hardware, & Software Bundle!

 

• Factory Euro M3 Headers
• Gaskets, manifold stud nuts
• Shark Injector Race Software

The original Euro headers for the E46 M3 are the original M3 header upgrade. They were the first set of headers we used back in 2001. These eliminate the original US catalytic converters in the stock US manifold (the Euro cats are under the car in the exhaust center section). With no restriction the Euro headers combined with Shark software will gain over 20hp from a stock US M3 (slightly less gain if using sport cats in section 1).

There are a lot of different headers for the E46 M3 but many of them are cheap copies of the true Euro headers. These are the genuine article without the quality issues and fitment nightmares of ultra-cheap imitations. Since these are Genuine BMW parts they are a direct fit to your engine with the proper flanges and routing with no interference with the air pump or other accessories. These can re-use the original exhaust studs on the engine and factory gaskets. New gaskets and hardware are included! Since these are straight off the Euro M3 they do not have the same port locations for the post-cat O2 sensors or EGT sensor. These are required even with Race software so they will need to be added by your installer.

The Shark Injector Race software has been calibrated specifically for headers and no cats. The software features tuning of the fuel, spark, VANOS, and throttle maps to unlock extra horsepower and torque with either 91 or 93 octane. We also raise the rev limit to 8,100 RPM. The throttle maps have been massaged to be smoother in normal mode and smoother and faster in Sport mode. This makes the car a lot easier to drive without the stumbling and bucking of the stock software. The Race software includes programming to run without cats. The post-cat O2 sensors and the EGT sensor must still be installed in the exhaust to prevent additional fault codes

These stainless tubular downpipes eliminate the largest restriction in the stock exhaust: the catalytic converters. These are a straight-through, cat-less downpipe system that replaces the stock downpipes on the F10 M5. Exhaust gas from a turbo exits the turbo housing with extreme force and velocity. Having a dense mass from the catalytic converter get in the way restrictions flow in a big way. By eliminating this restriction, the turbos work less which means more torque and horsepower and longer life for the turbos as well! Removing the cats also helps to reduce underhood temperatures and heat soak, which kills power especially at the track. These cat less downpipes remove all of the cats in the M5 exhaust so special race software will be required to keep the check engine light and fault codes from appearing.

Supersprint makes these tubular stainless headers for the Euro-spec E36 M3 but they make a great upgrade when fitted to highly tuned US models. The Euro exhaust uses larger diameter tubing because the Euro engines move so much air at high RPM. A US car with all of the typical bolt-on upgrades can also benefit from these larger pipes as it allows the engine to move the exhaust gasses easier. If you have the M50 manifold, cams, head work, or even forced induction, don't let your exhaust be your weakest link! Less work means more torque and horsepower are freed up to actually propel the car. These Euro headers are beautifully engineered and crafted from 304 stainless and feature mandrel bends and an equal length layout. An O2 sensor bung is built into each bank (or keep them plugged if not needed).

Note for all E36 models: the Euro exhaust has a very different layout than the US models. These headers are for the Euro M3 and will only fit US cars when used with the rest of the Euro exhaust system (center section with muffler) or a custom exhaust from these headers back.
Note for 96-99 models: these headers include O2 sensor bungs but no ports for the US secondary air pump. Therefore, these Euro headers are not intended for street-based cars and should only be used for racing or track use with special software, OBD-I conversion, or stand-alone engine management. In addition, the headers may have to be modified to properly block off the seconday air pump ports.

American Racing Headers is a performance exhaust manufacturer that specializes in high flow header systems. They have made a huge name for themselves since their creation in 2005 in the domestic world and are venturing into the Euro scene, now offering premium exhausts for BMW. Made 100% in the USA, located in Deer Park, New York, of 304 stainless steel and hand welded to ensure the best fitment possible, these headers and exhaust systems are perfect for high performance and long term durability. Within just a few years, the were noticed by the "Big-Three" auto giants in the US and were soon the Tier-One supplier of racing headers for the Ford Cobra Jet Mustang, General Motor's Copo Camaro, Chrysler's Drag Pack Challenger, and the Dodge ACR-X Viper.

Example of ARH E46 Header with Stock mid-section and Supersprint Rear Race Muffler (T#3467):


The stock S54 headers didn't exactly do the motor any justice when it came to performance. The catalytic converters were restrictive, the primary tubes were rather thin, and the dual desgin and basic collectors limited the amount of potential exhaust flow. ARH has taken action to resolve this issue and came out with their Performance Long Tube Headers.

Using 1-3/4" header primaries that are significantly larger than stock is the first major improvement. This allows immediate high flow and eliminates a potential restriction issue at higher RPM's. These are connected to a single piece mount made from 1/2" thick steel plate to prevent warping and are counter-bored so that the mounting is hassle free and lines up like OEM.

Next is the relocation of the catalytic converter. It is now located further down-stream after the collector. This manifold is available with or without the catalytic converter, giving you the option to build exclusively for the track or for split street and strip use. The cat has been upgraded to a performance 200-cell metallic-substrate catalytic converter for extreme durability and a long life.

The final major improvement is the custom in-house designed 6-to-1 merge collector. This is the most important part of the entire header system. The collector features a merge spike welded inside for a smoother transition and the primaries are arranged in a way that creates a vortex scavenging effect using the natural pulses of the engines exhaust. This helps pull the exhaust down to the the 3 inch choke, which increases the exhaust gases' velocity, then gradually increases back up to 3.5 inches.

All of these improvements taken into consideration lead to one final major result: More power throughout the RPM band in every gear, all the way to redline!

This racing header bolts up to the stock Section 2 mid-pipe and can be used with any cat-back exhaust! We recommend pairing this with your stock section two pipes and resonator and upgrading your rear muffler to the Supersprint Muffler (T#3467).

Product Features:

• 100% Made in the USA - Never Outsourced
• Made entirely of 304 stainless steel 
• 3/8" thick laser-cut flanges for a warp-free seal
• Hand-ported TIG welded inlets
• Optimized primary tube routing for superior fit and performance
• Merge collectors complete with welded scavenger spikes
• Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability 

If you decide you would like to purchase the catless headers: This part alters or deletes the emissions equipment on your car. Removing the primary cats will result in a check engine light and faults for the missing cats. Special software or modules will be required to prevent the codes but this setup will not be street legal. This was designed for race and track use only.

Eliminate the biggest restriction in the F30's exhaust by deleting the primary catalytic converter. On a track car, cats are no longer needed or wanted. They rob the turbo engine of power and torque, contribute excessive heat build-up, and lead to a total blockage if the catalytic material fails. This Supersprint cat-less downpipe solves all of that by having no restrictions through its oversized 76mm diameter piping. Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.

• Grade 10.9 metric hardware for high durability

Fits the following vehicles:
F10 F30 E89 BMW with N20 2.0L Engine

The original Euro headers for the E46 M3 are the original M3 header upgrade. They were the first set of headers we used back in 2001. These eliminate the original US catalytic converters in the stock UE manifold (the Euro cats are under the car in the exhaust center section). With no restriction the Euro headers will gain over 15hp from a stock US M3 (slightly less gain if using sport cats in section 1). 

There are a lot of different headers for the E46 M3 but many of them are cheap copies of the true Euro headers. These are the genuine article without the quality issues and fitment nightmares of ultra-cheap imitations. Since these are Genuine BMW parts they are a direct fit to your engine with the proper flanges and routing with no interference with the air pump or other accessories. These can re-use the original exhaust studs on the engine and factory gaskets. New gaskets and hardware are highly recommended (offered separately below). Since these are straight off the Euro M3 they do not have the same port locations for the post-cat O2 sensors or EGT sensor. These can be added by your installer or run special software to run without them. 

Since these headers replace the factory US catalytic converters they are sold for race and off-road use only. If your series requires a catalytic converter there are multiple options for sport cats in section 1. Special Race software will be required to prevent check engine lights and fault codes.

The cats in the stock US manifold are the biggest enemy in making more power from the S54. The cats as part of the stock header are a major blockage to airflow so removing them will unlock a lot of missing horsepower. Ideally, the best way to do this is with a set of Supersprint tubular headers. But if you want to keep your stock manifold and 'gut' the stock cats from them these pipes are the way to go. You can get a lot of the power gains of a true header system at a fraction of the cost. The stock cats are cut along an existing weld in each manifold and this piece is welded in place. Special software or modules will be required to keep fault codes and check engine lights from coming on. Bungs are preinstalled for the post cat O2 sensors. Any Supersprint section 1 piece will bolt on to these downpipes.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Fitment note: welding is required to install these pipes on the stock manifold. Once the stock manifolds are removed, cut along the existing seams for the stock cat and remove them. Then re-weld these pipes onto the original manifold.

Headers should be part of any M20 performance project or restoration. These Supersprint tubular headers are a larger diameter and have better flow than the stock exhaust manifolds and they make more power. And since the stock headers are known to be brittle and can crack over time these make for an excellent upgrade replacement.

This header system features an X-pipe after the headers to improve exhaust flow and scavenging. The X-pipe helps the exhaust gas mix and then flow into the rest of the exhaust. This header system has a bend in the outlets from the X-pipe to fit to the stock E30 catalytic converter (cut the stock E30 downpipes and these clamp in place). This makes them a direct swap from the stock manifolds and downpipes and an easy fitment for E30s with the stock exhaust.

When building a race or track car a free-flowing exhaust is critical. Removing restrictions and improving flow is key to making horsepower. That's even more important on car with turbos like the Z4 35i and Z4 35is. Reducing restrictions in the exhaust improves flow, which makes the turbos work more efficiently, freeing up horsepower and helping the turbos last longer. For the Z4 Supersprint makes these turbo downpipes without the catalytic converters. They are mandrel-bent and smooth flowing for a more power and better reliability. For the best performance and sound, combine these with the Supersprint section 1 straight pipes (sport catalytic converters also available, if required).

The factory 235/335/435 N55 exhaust system is pretty wide open with minimal restrictions - except for the catalytic converter. The factory cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a ultra high-flow HJS 100-cell metallic cat that flows considerably more than the stock ceramic part. It also uses bigger 80mm piping to minimize restrictions.

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

100-cell cats have 100 honeycomb cells per square inch. While still cleansing the exhaust somewhat this is basically a straight-through exhaust.

The original Euro headers for the E46 M3 are the original M3 header upgrade. They were the first set of headers we used back in 2001. These eliminate the original US catalytic converters in the stock UE manifold (the Euro cats are under the car in the exhaust center section). With no restriction the Euro headers will gain over 15hp from a stock US M3 (slightly less gain if using sport cats in section 1).

There are a lot of different headers for the E46 M3 but many of them are cheap copies of the true Euro headers. These are the genuine article without the quality issues and fitment nightmares of ultra-cheap imitations. Since these are Genuine BMW parts they are a direct fit to your engine with the proper flanges and routing with no interference with the air pump or other accessories. These can re-use the original exhaust studs on the engine and factory gaskets. New gaskets and hardware are highly recommended (offered separately below). Since these are straight off the Euro M3 they do not have the same port locations for the post-cat O2 sensors or EGT sensor. These can be added by your installer or run special software to run without them.

Since these headers replace the factory US catalytic converters they are sold for race and off-road use only. If your series requires a catalytic converter there are multiple options for sport cats in section 1. Special software will be required to prevent check engine lights and fault codes.

The air pump (also known as EGR system) has proven to be a headache for many BMW owners and it's one of the first things to go when building a racecar. The air pump is not required in many racing classes and deleting it saves some weight, complexity, and won't interfere with the rest of the exhaust or engine management system (deleting the air pump will require special programming in the ECU, a simulator, or a stand-alone engine management system). The M52/S52 manifolds are also a common upgrade on M50/S50US engines and these plates will be needed in those applications as well. When removing the air pump piping from the head two ports are left open that need to be blocked off. That's where this little plate comes in. They're made from stainless steel and include a new gasket to the head. They slide over the existing studs and secure with the existing nuts. Price is for a pair of block-off plates with gaskets.

Any amount of gain in exhaust flow is a plus. A common area of restriction are the exhaust headers. These exhaust headers replace the stock headers on the E36 BMW 6 cylinder to free up a bit more exhaust flow, making it easier for your car to breathe all the way up to redline, gaining both power and torque!

The pipes are made of 100% polished stainless steel with thick walls for high durability. The design creates a scavenging effect that helps to draw out much greater amount of exhaust, granting this set additional power that allows it to stand out from competitors for one of the best E36 exhaust header options on the market.

Features:

• Dyno-tested & Track Proven
• Bolts to existing Active Autowerke Track Pipe Section B
• Bolts directly to Active Autowerke E36 Race Exhaust
• Designed for race application (off road)
• Polished 100% 304 stainless steel construction
• Easy installation, no instructions necessary
• Two year warranty with free tech support

This header set is designed to be used with the full AA Race exhaust system or can be paired with AA's Track Pipe Rear Section (B) to fit any rear muffler that would fit the stock application.

Special Pricing! These Supersprint 'partial-stepped' headers for the Euro E46 M3, MZ3, and Z4 M are a replacement for the stock manifolds/cats. These are the tubular 'stepped' equal length headers (not the full racing stepped headers) - the header pipes increase in diameter the further they get from the engine until terminiating in a stock Euro-type flange. These stepped headers will bolt to the stock section 1 of the Euro exhaust. For making E46 M3 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears). Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and de-forming (any headers not made from stainless suffer from structural problems). Supersprint designs their headers with CAD programs and 50 years of exhaust tuning experience. These headers are an improvement over any 'Euro style' header on the market. This part is designed for the Euro market with the correct flanges for the Euro exhaust and the O2 and EGT sensor ports pre-installed. Special software or stand alone engine management would be required to keep check engine and fault codes from appearing. Software is recommended to maximize the performance gains from this header upgrade.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Active Autowerke has been an industry leader in engineering high quality BMW performance products for over 30 years. Dedicated to improving performance with the highest quality products, Active Autowerke is synonymous with making power. Their philosophy on developing refined BMW performance parts, with power in mind, and providing them to a large BMW community can be best characterized by our F80 M3 and F82 mid pipe – a valuable addition to our F8X BMW collection.

The Active Autowerke F8X Mid Pipe was specifically designed to eliminate the highly restrictive nature of the OEM F80 M3 and F82 M4 mid pipe – thus creating optimal exhaust flow and drastically improving performance. In addressing the annoying sound ( described by many like that of a weed-eater ) we needed to better understand the issue. After much research and testing we discovered the synchronization of the Turbos as the main factor in the sound. The solution was a single mid pipe which eliminated much of the annoying sound. The next challenge was making a large 3.5" pipe ( needed for optimum performance ) fit without ground clearance issues - thus the oval pipe. Engineered for an exact fit on both the F80 M3 and F82 M4, the difference in power with this mid pipe will be noticeable the moment it is installed!

Upon analyzing the F8X exhaust, Active Autowerke came to the decision that they can accomplish more with much less – therefore designing the F80 M3 and F82 M4 exhaust started with the highly restrictive mid pipe. With their design, they were able to drastically increasing exhaust flow, while virtually eliminating the "dueling 3-cylinders" sound.

Features:

• 18+ WHP over stock*
• 30+ LB-FT over stock*
• Improved performance from less back pressure
• Deeper & throatier exhaust note
• Less restrictive, more free flowing
• Lighter weight than factory system
• Quicker turbo spool
• Increased low end and mid-range power
• Single-pipe design eliminates cheap “weed-eater” sound from factory exhaust

BMW introduced a new valvetronic, single turbo version of its direct-injection engine for the F-Chassis models, the Active Autowerke N55 downpipe for the M235i, 335i, 435i and M2 helps unleash some of the potential that is restricted by the OEM downpipe.

Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the N55 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke F-Chassis N55 Signature down pipe utilizes 3.5” diameter stainless steel piping in order to provide more power, quicker spool, and extreme durability. 

A fabricated a 3.5" V-Band flange in the middle of it to create a truly modular design for any enthusiasts that would like to upgrade to a complete 3.5" exhaust later down the road. The OEM downpipe shrinks down to under 3" where it meets the stock exhaust. They've inserted the 3.5" flange so that if you have an M2 you can later upgrade to our complete 3.5" turbo back system, or if you have a M235i, 335i or 435i you'll have the option to create your own 3.5" turbo back system! AA's downpipe is the perfect addition for any F-Chassis N55 and especially those with an upgraded turbo system!

FEATURES:

• Designed to be as unrestrictive as possible
• 3.50" diameter piping allows for maximum power output
• Quicker turbo spool
• Easily bolts-on – no cutting or welding required
• Durable construction from 304 stainless steel
• Precise fitment
• Modular design for later upgrades

Special pricing! Free ground shipping! The biggest restriction in the exhaust is from the stock headers themselves. The factory header/exhaust manifold contains the catalytic converters. The design is not very conducive to exhaust flow so they rob the engine of horsepower and torque. One way to get that back is to use a non-restrictive exhaust header like this Supersprint. It does not contain a catalytic converter so the shape and size of the tubing can be optimized for the M54 3.0-liter inline-6. A catalytic converter is still recommended but installed in place of the factory center resonator.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Experience the latest design innovation from Supersprint for the E46 M3 -- 'stepped' design headers. While the technology has been in widespread use in Formula 1 for awhile, this is the first application of a stepped design on the E46 M3. In an engine that is tuned as much as the S54, airflow management is critical in getting big horsepower numbers from the exhaust. The Supersprint design is the next step in innovation in header design. By slightly increasing the size of the pipe diameters as the exhaust system moves away from the engine, the exhaust can flow more air. Supersprint's design is tuned specifically for the S54 engine which is important in making more power without losing low-end torque. The headers merge into a precision-fit merge collector. After the headers, the stepped piping size continues into the Supersprint section 1 with or without cats. The section 1 must be purchased separately. Any section 2 and rear muffler can be used with the Supersprint section 1. Our most-popular package for track cars is for the stepped headers with no cats (straight pipe) but cats are available for people who want to keep emissions in check (or if your rules require them). Total horsepower gain with the complete system over a US M3 would be more than 30hp.

Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

We also recommend using this system on the M3 with special software. The Shark Injector software has been specifically designed for cars running headers but no cats. The software "turns down" the readings from the rear O2 sensors and modifies the tolerances for the EGT sensor. Using an exhaust without the cats and proper software will surely cause a Check Engine Light. Click here for more info on the software.

One area where the US M5/M6 is different than a more-powerful Euro-spec model is in the exhaust. The US M5/M6 got a header design with smaller pipes that is more restrictive. These Supersprint headers are based on the Euro design (no longer available through BMW USA) but are slightly larger tubes for better performance. The stepped design is a favorite of M3 header designs and originated in Formula 1 engines. These headers also feature Supersprint's precision-engineered merge collectors on each bank that greatly improves exhaust flow and does not impede velocity.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Fitment note: this system is based on the Euro design with 3-bolt flanges (the US used 2-bolt flanges). You will need the factory Euro center section or the Supersprint center section for this to be a direct bolt on. We recommend using this with the full Supersprint system (front center pipes, rear center resonator, and rear muffler) for the easiest install and the best sound.

Once you have your turbo system functioning properly, you have to figure out what you want to do with the exhaust from the wastegate. In order to keep your engine bay clean but retain the fun turbo sounds, AR Design has designed a dump tube kit that specifically is made for their E36 Turbo Manifold that redirects the exhaust gases down and out underneath of the vehicle. this prevents carbon build up in the engine bay and gives you the louder exhaust note you are looking for when the wastegate is activated.

Specializing in manufacturing premium aftermarket components, AR Design has come to be known for their exceptionally high quality. From the choice of the materials used, the expert craftsmanship that goes into each part, and the fact they manufacture their parts all here in the United States, it points to their dedication to make only the best parts available on the market.

Deleting the secondary air pump from your exhaust? This plate is the perfect touch! The air pump (also known as EGR system) has proven to be a headache for many BMW owners and it's one of the first things to go when building a racecar. The air pump is not required in many racing classes and deleting it saves some weight, complexity, and won't interfere with the rest of the exhaust or engine management system (deleting the air pump will require special programming in the ECU, a simulator, or a stand-alone engine management system). When removing the air pump valve from the head the port is left open that needs to be blocked off. That's where this little plate comes in. This is actually a factory BMW part and includes a new steel gasket to the head. It will slide over the existing studs and secure with the existing nuts.

For a true racing car, the biggest restriction in the exhaust system is the catalytic converters. On modern BMWs there are often two sets - a primary in the header/downpipe and a secondary further back in the exhaust. Removing these restrictions with a cat-less downpipe and straight pipes has enormous benefits for a track or race car: remove the restriction which unlocks huge power and torque gains, less heat (which can reduce power output), zero complication from a clogged or blocked catalytic converter, and less weight. These Supersprint M3/M4 cat-less downpipes are made from stainles steel and have no cats and mandrel-bent pipes for the best flow out the turbos. These will bolt on to the Supersprint or a stock section 1 front pipes. Special software or stand-alone engine management will be required to keep the check engine light and faults from appearing.

Special pricing! Free ground shipping! This turbo down pipe for the 135i and 335i is manufactured from 304 stainless steel using all mandrel bent tubing and each pipe is 65mm in diameter resulting in ultra low backpressure, assuring instant turbo spool up for maximum torques and horsepower gains for your 135i or 335i. The results of installing a complete turbo to tail pipe Supersprint system are a phenomenal 26 hp with a torque gain over 20 lb/ft.

The stock down pipes cause a major restriction in the exhaust flow. BMW's solution to deal with the limited space in the engine compartment is to crush the turbo outlet tubes to reduce the size of the tubing. Doing this created undesirable backpressure. For emission purposes the factory also incorporated built-in pre-cats directly after the turbo outlet ports. This make the exhaust gas backpressure rise to extremely high levels at all rpm and engine loads. This design retains excessive heat in the engine and affects performance in a negative way. The design of the Supersprint down pipes takes advantage of even the smallest space available and frees the exhaust gas flow dramatically. The SS pipe cross section (no crushed pipe) remains constant all along the down pipes and the pre-cats are totally eliminated.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level.

Pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one.

For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F80 M3 and F82 M4 Collection, these F8X downpipes, is a true testament to our outlook on creating innovative products with performance in mind.

The F8X downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory F80 M3 and F82 M4 downpipes – therefore reducing radiant heat and increasing performance.

The initial prototype design didn’t include the flex joints you see in the images above. Without these flex joints, the prototypes created an annoying vibration from within the cabin. They quickly realized the necessity of including flex joints into the design and went back to the drawing board. The works of art you see above are a culmination of years of experience engineering top-notch BMW exhaust products.

Made from 1.3-1.5mm thick 304 stainless steel, these F80 M3 and F82 M4 downpipes are finished with a White Lightning Exhaust Coating (performance enhancing, ceramic coating) from Swain Tech Coatings. Developed for precise fitment on both the F80 BMW M3 and F82 BMW M4, the difference in performance will be noticeable the moment you leave your driveway!

Unlike many of the cosmetic exhaust coatings, Swain Tech Coating’s White Lightning Exhaust Coating is a REAL ceramic coating – an exceptional insulating material. Since White Lightning is such a great insulating material, it is applied nearly five times thicker than a cosmetic coating. Additionally, White Lightning has performance enhancing benefits that cannot be matched by other cosmetic exhaust coatings.

Applied in a molten state, the ceramic coating bonds directly to the exhaust component. Typically a White Lightning coating can reduce radiant heat by roughly 35-55% - thus reducing engine bay and intake air temperatures.

“A 10°F reduction in intake air temperature provides a 1% increase in horsepower. A 30°F reduction equates to a 3% horsepower increase.” – Swain Tech Coatings

Furthermore, the insulating properties of the coating keep exhaust gases at the highest temperature possible creating greater exhaust gas velocity and higher efficiency. With the melting point of the White Lightning coating being over 3,000°F, you will not have to worry about damaging the coating.

The most remarkable feature of the White Lightning coating is how quickly it dissipates heat. Less than an hour after running hard, the downpipes will be cool to the touch allowing you to work around them without being concerned about scalding yourself.

Features:

• 10-15 HP increase*
• Flex joints to dampen vibration
• Optional White Lightning Exhaust Coating by Swain Tech Coatings
• 304-stainless
• Quicker turbo response
• Less restrictive, more free flowing
• Improved low-end and mid-range performance
• Made in USA
• Lighter weight than factory downpipes

*Performance gains when paired with Active Autowerke F8X Mid Pipe

**Note: For Off-Road or Race Use Only

Free ground shipping! One key to making power from the S85 V10 is eliminating the factory catalytic converters in the manifold. Ideally, the best way to do this is with a set of Supersprint tubular headers. But if you want to keep your stock manifold and 'gut' the stock cats from them these pipes are the way to go. The stock cats are cut along an existing weld in each manifold and this piece is welded in place. Special software or modules will be required to keep fault codes and check engine lights from coming on. O2 sensor and EGT sensor bungs are pre-installed. Any Supersprint section 1 piece will bolt on to these downpipes.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Section 1 / Catalytic Converter Options
You have a few different options for the exhaust immediately after the headers (known as 'section 1'):

• connecting pipes to stock section 1 cats*
• Supersprint section 1 test pipes (no cats)**
• Supersprint section 1 metallic sport cats**

** - these layouts are sold expressly for race or on-track use only. Special software may be required to prevent fault codes and other conditions.

The factory M5/M6 exhaust system is very wide open with minimal restrictions - except for the catalytic converters. The factory ceramic cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a high-flow HJS 200-cell metallic cat that flows considerably more than the stock ceramic part. This cat downpipe is for the right bank.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

Factory downpipes and their catalysts are a choke point for exhaust gases. This restriction slows turbocharger spool and reduces efficiency, and has a significant impact on power. When modifying their N54, most enthusiasts quickly find OEM downpipes offer insufficient performance as power levels are increased, resulting in disappointing results from other modifications. While some find catless downpipes to be the answer, their benefits are increasingly failing to outweigh the downsides when used on the street. Exhaust volume is increased (combined with a full exhaust may be too much for sensitive ears), check engine lights are frequently illuminated, and emissions are greatly increased (a problem for the environment and in passing emissions testing).

Turner engineers designed downpipes that met a happy compromise - excellent flow with high performance 48-state legal catalytic converters. By utilizing cats, these downpipes offer much lower emissions than catless products (and in many cases, no check engine light), with little sacrifice to performance versus their catless counterparts. These high-flow units feature a 3" inlet, followed by a series of smooth radius bends and efficient catalyst, exits as a 2.5" to retain compatibility with popular cat-back exhausts (as well as factory exhaust piping).

We confirmed power and efficiency improvements are present on both a stock tune with even greater power to be found versus factory downpipes while utilizing a simple ECU tune. These gains were confirmed on our in-house Mustang AWD-500 dynamometer while running an off-the-shelf (no tuning trickery in these numbers) Cobb Stage 1 tune:

Stock downpipes wheel horsepower: 314hp @ 5700rpm
Stock downpipes wheel torque: 386ft/lb @ 4000rpm

Turner downpipe wheel horsepower: 334hp @ 6000rpm
Turner downpipe wheel torque: 390ft/lb @ 4100rpm

Max gains:
36hp @ 6500rpm
23ft/lb @ 6000rpm

Product features:

• Large diameter 3" tubing and 200 cell high-flow catalytic converters - significantly reducing flow restriction found on factory downpipes
• 304 stainless steel with beautiful quality TIG welds
• Precise fitment - no wrestling to install, listening to clunks, or feeling vibration associated with ill-fitting downpipes
• Uses factory clamp 11657620508 and factory gaskets 18307553601 (x2) and 18307553603 (x2). Install kit available here.

The Active Autowerke BMW E46 M3 Header is designed to increase exhaust flow without losing power which can sometimes be a tricky proposition. These headers are developed to create optimum flow and eliminate restriction that rob much desired horsepower. Following the famed BMW E46 M3 CSL headers, each individual header runner of the Active Autowerke header is cut to a matched equal length to ensure a consistent exhaust scavenging (tolerance in lengths vary by bends to a mean average of 10-20mm). 

They are suitable for naturally aspirated and supercharged forced induction applications, Active Autowerke’s BMW E46 M3 Headers are made out of 100% 304 stainless steel, making durability a worry of the past.

Each and every BMW E46 M3 header is test fitted to an actual BMW E46 M3 motor stand. There are fixtures to simulate engine bay features like inner fender and frame rail. Oxygen sensor placements are also checked for correct interference.     

To eliminate the smell of un-burnt fuel and control the natural raspiness of the S54 motor, pair these headers with the Section 1 pipe with 100 cell race cats.

FEATURES:

• Creates optimum flow and eliminates restriction
• Matched equal length runners delivers a consistent flow 
• Dyno Tested to provide improved HP and torque gains
• Made from 100% 304 stainless steel construction
• Bolt On Design with Precise Fitment 
• BMW OEM Style fitment 
• Complete hardware, includes all necessary gaskets and nuts

For a true racing car, the biggest restriction in the exhaust system is the catalytic converters. On modern BMWs there are often two sets - a primary in the header/downpipe and a secondary further back in the exhaust. Removing these restrictions with a cat-less downpipe and straight pipes has enormous benefits for a track or race car: remove the restriction which unlocks huge power and torque gains, less heat (which can reduce power output), zero complication from a clogged or blocked catalytic converter, and less weight. These Borla M3/M4 cat-less downpipes are made from stainles steel and have no cats and mandrel-bent pipes for the best flow out the turbos. These will bolt on to the Borla or stock section 1 front pipes. Special software or stand-alone engine management may be required to keep the check engine light and faults from appearing.

Borla is committed to providing world-class exhaust products that exceed customer expectations. To accomplish this, they have a facility complete with a state-of-the art test and development center. Pioneering a variety of improvements in the design of performance exhaust systems, Alex Borla currently holds several US patents for innovative exhaust system technology. Borla has won numerous "Best New Product" awards in the industry.

One of the biggest restrictions on the N52 engine is in the exhaust system. The 525i, 528i, and 530i use primary and secondary catalytic converters in the exhaust and the biggest blockage comes from the primary cats located in the exhaust manifold. These Supersprint tubular headers remove the primary cats entirely, speeding up exhaust flow, and releasing more horsepower and torque. These headers will bolt on to the stock secondary cat section or a new set of Supersprint metallic sport cats.

Adding headers and removing catalytic converters from the exhaust is one of the top things to do to make more power. The factory put the cats in the stock exhaust manifold which restricts exhaust flow. But any race or track car will want to run without cats to gain the most power and torque. These Supersprint stainless headers are a true tubular, equal length design that bolt up for an immediate power gain. With no cats and a race exhaust you can expect to gain 20-25hp over the stock exhaust setup. Power gains with a cat section depend on the type of cat.

The factory 35i exhaust system is pretty wide open with a minimal of restrictions - except for the catalytic converter. The factory cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a high-flow HJS 200-cell metallic cat that flows considerably more than the stock ceramic part.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

Active Autowerke is proud to bring you our hand made Signature N63 Downpipes for the twin-turbo V8 BMW .

A turbo impeller wheel speed is mostly limited by the exhaust back pressure within the system. If one could eliminate some or most of this exhaust back pressure, the turbo will spool that much faster and effortlessly resulting in quicker engine revs and increased HP. The Active Autowerke Signature down pipes are designed with the intent to maximize power. These down pipes are created with the least amount of restrictions possible by utilizing a full 3" piping throughout with the least amount of bends possible. What you will experience is a faster, more responsive engine because the turbo impeller now has the ability to spool that much faster. The end result is more power.

Made from 304 stainless steel the handmade construction process ensures a robust and durable exhaust that will provide trouble free performance with the longevity to match. 

FEATURES:

• Designed with less restrictive curves and more straight flows 
• Full 3.00" diameter piping throughout allows for maximum power output
• Quicker turbo spool 
• Precise fit installation
• Full down pipe exhaust support braces relieves load bearing stress
• Installation instructions included

Fits the following vehicles:

One of the keys to gaining power in any turbo engine is from reducing restrictions. By replacing the factory catalytic converter with a freer-flowing piece you are picking up additional power and still keeping the exhaust gases clean. This downpipe for the N20 engine is a direct replacement for the stock downpipe and includes a metallic catalytic converter. Supersprint's dyno testing revealed a 15hp/10ft-lbs increase using this downpipe and the rest of their exhaust system.

This kit includes the Active Autowerke M3 Catless Header Set and the Section 1 Pipes with High Flow 100-cell catalytic converters.

The Active Autowerke BMW E46 M3 Header is designed to increase exhaust flow without losing power which can sometimes be a tricky proposition.

These headers are developed to create optimum flow and eliminate restriction that rob much desired horsepower.

They are suitable for naturally aspirated and supercharged forced induction applications, Active Autowerke’s BMW E46 M3 Headers are made out of 100% 304 stainless steel, making durability a worry of the past.

Combine the Active Autowerke Exhaust SECTION 1 with a pair of Hi Flow 100 cell metallic catalysts and you have part of a winning combination for your BMW.

The Active Autowerke Exhaust SECTION 1 only comes into play if your vehicle already has a performance header already installed.  One will experience a high smell of unburnt fuel. (due to the open exhaust w/o any catalysts) and development of a RASPY like sound of which the BMW S54 engine is notorious for with the BMW Stock Section 1 when equipped. This raspy like sound is a matter of engine sound harmonics at a specific RPM range, a sort of resonance that is very loud and noticeable when the engine is revving at or above 4,000 rpm. With the Active Autowerke Exhaust SECTION 1 installed, the BMW performance gains are about the same as running the factory section 1. However, that's impressive considering the exhaust flow is also being filtered while running through a pair of 100 cell catalysts. The power and performance is still there. In addition, the smell of un-burnt gas? Gone. The excessive exhaust rasp? Gone.

**These section 1 pipes are not set up for direct O2 sensor fitment and are therefore not considered legal for street use. Professional installation of O2 sensors and sensor bung ports may allow these to prevent check engine lights and meet emissions requirements, but this is not guaranteed. Please check with state and local law before altering the exhaust system components of a street driven vehicle.

This part alters or deletes the emissions equipment on your car. Removing the primary cats will result in a check engine light and faults for the missing cats. Special software or modules will be required to prevent the codes but this setup will not be street legal. This was designed for race and track use only. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

FEATURES:

• Creates optimum flow and eliminates restriction
• Matched equal length runners delivers a consistent flow 
• Dyno Tested to provide improved HP and torque gains
• Made from 100% 304 stainless steel construction
• Bolt On Design with Precise Fitment 
• BMW OEM Style fitment 
• Complete hardware, includes all necessary gaskets and nuts
• Two year warranty

Fits all BMW E46 M3's.

Special Pricing! Adding headers and removing catalytic converters from the exhaust is one of the top things to do to make more power. The factory put the cats in the stock exhaust manifold which restricts exhaust flow. But any race or track car will want to run without cats to gain the most power and torque. We used these on our in-house 330i ZHP project car . These Supersprint stainless headers are a true tubular design that bolt up for an immediate power gain. With no cats and a race exhaust you can expect to gain 20-25hp over the stock exhaust setup. Power gains with a cat section depend on the type of cat.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Section 1 / Catalytic Converter Options
You have a few different options for the exhaust immediately after the headers (known as 'section 1'):

	Supersprint section 1 metallic sport cats*
	Supersprint section 1 test pipes (no cats)**

* - you will need to have the rear O2 sensors extended to the new location of the cats.
** - cat-delete is sold expressly for race or on-track use only. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.

The factory 235/335/435 N55 exhaust system is pretty wide open with minimal restrictions - except for the catalytic converter. The factory cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a ultra high-flow HJS 200-cell metallic cat that flows considerably more than the stock ceramic part. It also uses bigger 80mm piping to minimize restrictions.

American Racing Headers is a performance exhaust manufacturer that specializes in high flow header systems. They have made a huge name for themselves since their creation in 2005 in the domestic world and are venturing into the Euro scene, now offering premium exhausts for BMW. Made 100% in the USA, located in Deer Park, New York, of 304 stainless steel and hand welded to ensure the best fitment possible, these headers and exhaust systems are perfect for high performance and long term durability. Within just a few years, the were noticed by the "Big-Three" auto giants in the US and were soon the Tier-One supplier of racing headers for the Ford Cobra Jet Mustang, General Motor's Copo Camaro, Chrysler's Drag Pack Challenger, and the Dodge ACR-X Viper.

Sound Example from American Racing Headers:

As shown above, their E9X Header to Axle exhaust system's are perfect for giving your vehicle both a much more aggressive sound when paired with stock or aftermarket exhausts and unleashing the potential power of your 4.0L S65 V8.

The first parts down the line are their signature high flow headers! Using header primaries that are larger than stock and merge collectors that are in-house designed to improve flow as much as possible using a vortex scavenging design, these headers allow a significant improvement in total exhaust flow resulting in higher torque and horsepower numbers throughout the RPM band. The primary tubes come in 2 sizes: 1-5/8" diameter or 1-3/4" diameter. 1-5/8" primaries offer a moderate improvement over stock allowing for less restriction directly at the head and down to the collector. This size will better benefit vehicles that are mostly stock and with a tune and performance intake. 1-3/4" primaries offer a more sizable improvement, allowing for vehicles built much more aggressively to benefit greatly. Vehicles with performance cams, higher performance tunes, and other heavy modifications will be able to efficiently expel exhaust gases thanks to the lower restriction and will be able to see much higher numbers on a dyno and feel a difference on the street or strip. 

After passing through the manifold, the exhaust gases come to the second component of this performance system, the 3" X-pipe that is available with or without catalytic converters. X-pipes are great for two reasons: More even exhaust flow throughout the power band, thus improving engine efficiency, and an steadier exhaust note that gives off a super-car feel instead of the traditional pulsating that gives your car an old muscle car sound. This helps express the natural sound of the exhaust both at idle and under heavy acceleration. Catalytic converters are the next option to choose from. Building a car for the track only? Cat-less is the answer. Looking to drive your vehicle both on and off the track? The 200-cell high flow catalytic converters keep you both road legal and they are virtually restriction free for continued high flow exhaust. In addition, the x-pipe is built with O2 bungs installed, ready for your sensors to be reinstalled.

Last in line is the center section with two 3" exhaust pipes available with or without resonators. Some people prefer to eliminate the resonators to get the most aggressive growl out of their exhaust as possible, and others like to keep these in place to help eliminate high RPM drone that can become slightly irritating when driving long distances. More of a personal preference, this just allows for even further exhaust customization.

Product Features:

• 100% Made in the USA - Never Outsourced
• Made entirely of 304 stainless steel 
• 3/8" thick laser-cut flanges for a warp-free seal
• 1-5/8" or 1-3/4" exhaust header primaries for higher flow
• Hand-ported TIG welded inlets
• Optimized primary tube routing for superior fit and performance
• Merge collectors complete with internal welded scavenger spikes
• Catted systems feature 200 cell metallic substrate catalytic converters for extreme durability
• High flow x-pipe for exhaust flow balance and smoothness.
• Dual stainless 3" center-section pipes available with or without resonators
• Hardware for assembly included

If you decide to purchase the catless system: This part alters or deletes the emissions equipment on your car. Removing the primary cats will result in a check engine light and faults for the missing cats. Special software or modules will be required to prevent the codes but this setup will not be street legal. This was designed for race and track use only.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

The factory header system on the M5/M6 V10 is nicely designed - except where the primary tubes join together. Here the factory tubes are crushed in size and joined in narrow housing ahead of the catalytic converters. Supersprint has designed a fully tubular header and collector system that is fully mandrel bent and makes no compromises. They even patented the design. With a complete exhaust system, we recorded gains of over 60hp! These headers can be connected to either a factory secondary cat or a Supersprint high-flow metallic cat.

What sets these headers apart from others is the expertise and craftsmanship from Supersprint in Italy. These are 100% stainless steel headers with true mandrel bends. It's a carefully engineered header and merge collector design with superior craftsmanship to other systems (sometimes knockoffs to the original Supersprint). Supersprint spends considerable time in R&D, experimenting with piping sizes and layouts to get the most horsepower gain (confirmed with their in-house dyno). Fitment is also a key consideration and this is where Supersprint's commitment to quality fabrication and construction set them apart from cheaper systems.

For over 30 years, Active Autowerke has been the one to turn to for high quality BMW performance products. Committed to enhancing the performance of BMWs through the highest quality products is what Active Autowerke is all about. The newest addition to our BMW F80 M3 and F82 M4 Collection, these F8X downpipes, is a true testament to our outlook on creating innovative products with performance in mind.

The F8X downpipes are strategically engineered to virtually eliminate the immensely restrictive characteristics of the factory F80 M3 and F82 M4 downpipes – therefore reducing radiant heat and increasing performance.

The initial prototype design didn’t include the flex joints you see in the images above. Without these flex joints, the prototypes created an annoying vibration from within the cabin. They quickly realized the necessity of including flex joints into the design and went back to the drawing board. The works of art you see above are a culmination of years of experience engineering top-notch BMW exhaust products.

Made from 1.3-1.5mm thick 304 stainless steel, these F80 M3 and F82 M4 downpipes have a stainless finish. Developed for precise fitment on both the F80 BMW M3 and F82 BMW M4, the difference in performance will be noticeable the moment you leave your driveway!

Features:

• 10-15 HP increase*
• Flex joints to dampen vibration
• Optional White Lightning Exhaust Coating by Swain Tech Coatings
• 304-stainless
• Quicker turbo response
• Less restrictive, more free flowing
• Improved low-end and mid-range performance
• Made in USA
• Lighter weight than factory downpipes

*Performance gains when paired with Active Autowerke F8X Mid Pipe

**Note: For Off-Road or Race Use Only

Eliminate the biggest restriction in the F30's exhaust by deleting the primary catalytic converter. On a track car, cats are no longer needed or wanted. They rob the turbo engine of power and torque, contribute excessive heat build-up, and lead to a total blockage if the catalytic material fails. This Wagner cat-less downpipe solves all of that by having no restrictions through its oversized diameter piping. Special software, or stand-alone engine management, will be required to keep emissions fault codes and check engine lights from appearing.

Features:

• made out of high quality stainless steel 1.4301 (SS304)
• 100% perfect fit, replace OEM
• less thermal load on the turbocharger
• more power by reducing back pressure
• significantly more torque
• connection diameter 105mm

Free ground shipping! The factory M5/M6 exhaust system is very wide open with a minimal of restrictions - except for the catalytic converters. The factory ceramic cat is the biggest restriction so any exhaust work to gain more power is going to have to involve replacing it with something freer-flowing. Supersprint's downpipe incorporates a high-flow HJS 200-cell metallic cat that flows considerably more than the stock ceramic part. This cat downpipe is for the left bank.

Supersprint metallic sport catalytic converters are sourced from HJS of Germany. For 30 years HJS has been supplying motorsports teams with sport cats when rules required them. HJS is now a worldwide leader in sport cat technology and performance. Rally cars, German DTM, and Formula 3 all rely on HJS for clean, reliable horsepower. Supersprint works closely with HJS to spec a catalytic converter that is correct for the vehicle and engine package. This allows for a substantial increase in flow but which, at the same time, keeps the environmental specs within European limits. With any high-flow catalytic converter, special software or other work may be required to keep emissions fault codes and check engine lights from displaying. Supersprint catalytic converters are sold for track and other off-road uses only.

Adding headers and removing catalytic converters from the exhaust is one of the top things to do to make more power. The factory put the cats in the stock exhaust manifold which restricts exhaust flow. But any race or track car will want to run without cats to gain the most power and torque. We used these on our in-house 325i project car on our way to 272hp. These Supersprint stainless headers are a true tubular, equal length design that bolt up for an immediate power gain. With no cats and a race exhaust you can expect to gain 15-20hp over the stock exhaust setup. Power gains with a cat section depend on the type of cat.

Section 1 / Catalytic Converter Options
You have a few different options for the exhaust immediately after the headers (known as 'section 1'):

 

Stock Section 1 Cats*Sport Cats*Straight Pipes**

* - you will need to have the rear O2 sensors extended to the new location of the cats. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.
** - any cat-less section is sold expressly for race or on-track use only. Special software or stand-alone engine management may be required to prevent fault codes and other conditions.

In your quest for the ultimate boost and power gains from your twin-turbo N54 your plans should include a set of cat-less downpipes. Removing the catalytic converters opens up the exhaust flow and with less restriction the turbos can spin and spool easier. This means boost comes in sooner and with more force. More power is available with proper software tuning.

The CP-E downpipes are among the finest crafted turbo downpipes we have seen for the N54 engine. They use a CAM/CAD process, and automated manufacturing, that ensures a tight and precise tolerance for fitment and construction. This attention to detail and craftsmanship will never be found on the cheap auction sites. These pipes are made from 304 stainless steel, 3" diameter at the inlet and then tuned piping down to meet the stock exhaust section. The piping is not only mandrel bent but also features fewer joints and welds than other downpipes that can disrupt flow. These are a direct replacement for the stock downpipe and cat section, including fitment for Xi AWD models. No permanent modifications are made and the upgrade is completely reversible. You retain your factory oxygen sensors. Add a O2 bung kit if you wish to install a wideband sensor on the downpipe.

Pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one.

50 STATE LEGAL! A Turner Motorsport developed part, our "shorty style" performance headers are CAD designed to be equal length and flow with equal pressure, made from 100% stainless steel, and finished in a 2-stage ceramic coat. The layout and tube sizes were designed to increase mid range torque and power with additional increases at the top end. Bolt these on to your stock E36 or Z3 for a instant 12 ft-lb torque and a 9 HP gain - we often see more on modified engines!

Unlike other headers on the market, the TMS Shorty headers bolt directly to the stock BMW catalytic converter! Gaskets and new exhaust hardware are also available (see below). Stainless steel construction retains heat much better than the mild steel often found in cheaper copies of our header. This results in increased exhaust velocity. Our headers are also TIG welded on the outside and use an 'under-over' construction into the merge collector so exhaust flow is not disrupted. Don't be fooled by cheap, non stainless imitations that sell for less. Trust us - you get what you pay for. If you want the best shorty header on the market, this is the one.

For OBD-I for 1992-1995 325i, M3 3.0, and later cars converted to OBD-I (single O2 sensor and air pump removed)

Optional gasket sets include:
Manifold to cylinder head gaskets
Manifold to catalytic converter gaskets

Turner Shorty Headers fit the following BMWs (left-hand drive models only):
1992-1995 E36 BMW 325i 325is 325ic M3

These downpipes are resonated to help even out the exhaust flow and reduce drone at high RPMs.

These are available with a stainless steel finish or coated with a ceramic coating rated up to 2000 degrees Fahrenheit. This helps keep the heat from radiating into the engine bay, keeping air intake temperatures much lower! The ceramic coatings are available in 2 finishes, Silver and Black.

*This part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to Turner Motorsport. You can download the waiver here.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Fits the following engines:
M60

Fits the following chassis:
E31, E32, E34

These N54 downpipes feature larger piping and cat sections that are freer-flowing than the original cats for better flow and less backpressure. By removing exhaust restrictions the turbos can spool up faster which makes more boost sooner. With additional tuning, more power is available. There are downpipes that delete the primary cats and can leave the exhaust with a dirty and awful smell. These CP-E downpipes are built with a set of sport cats to keep the exhaust cleaner.

The CP-E downpipes are among the finest crafted turbo downpipes we have seen for the N54 engine. They use a CAM/CAD process, and automated manufacturing, that ensures a tight and precise tolerance for fitment and construction. This attention to detail and craftsmanship will never be found on the cheap auction sites. These pipes are made from 304 stainless steel, 3" diameter piping from the inlet to the cat, and tuned piping down to meet the stock exhaust section. These are a direct replacement for the stock downpipe and cat section, including fitment for Xi AWD models. No permanent modifications are made and the upgrade is completely reversible. You retain your factory oxygen sensors. Add a O2 bung kit if you wish to install a wideband sensor on the downpipe.

Pick up a Cobb AccessPort programmer to go along with these downpipes. Additional tunes are available that will get the most out of this upgrade. Not only will the Cobb AP increase horsepower and torque but special programming is available to keep fault codes, check engine lights, and limp mode from disrupting your day. It has other features too such as data logging and diagnostic fault code reading and clearing. The Cobb AP is the most sophisticated programming tool available for the 135/335 and no tuning plan should be without one..
