BMW E46 Performance Headers & Downpipes

BMW E46 Performance Headers & Downpipes Headers are a bolt-on component that will make a huge improvement in how your BMW performs. As a replacement for your factory BMW exhaust manifold, our BMW headers provide a more direct path for exhaust gasses leaving your engine. Headers prevent your BMW's exhaust pulses from "fighting" one another as they leave the head. The end result is that BMW headers give you more power and torque, and you'll love the high-winding top end push that a free-breathing engine exhibits. BMW headers are a must-have if you're doing any engine modifications on your vehicle. Along with a cold air intake, BMW headers provide the free-flowing exhaust necessary to get the most power out of your motor.

AR Design Dump Tube Kit - M5x S5x E36

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.

E46 M3 aFe Twisted Steel Stainless Performance Headers

aFe Power's new Race Only Twisted Steel Headers deliver an astounding 12hp and 16lbs. X ft. torque while outflowing the factory exhaust manifolds. The headers are constructed of near equal length 1.625" / 1.6mm 304 stainless steel tubing with 3/8" thick CNC machined flanges to ensure a leak free seal. To eliminate dead space that can cause turbulence and hinder flow that formed collectors are prone to produce, true merge collectors and optimized tube lengths are used for true pulse control technology improving flow and performance. 100% TIG-welded, the smooth curves and increased diameter of this header helps remove restriction and keeps exhaust gas flowing smoothly for improved performance and durability. All components are supplied for a hassle-free installation with no modifications necessary.

Features:

  • Tig-Welded: 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
  • Retain Factory Sensors: aFe has designed this system to retain all your factory sensors for a hassle free installation.
  • Mitered Collectors: Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.
  • CNC Machined Flanges: Flanges are CNC machined not only to be visually appealing but for a precise fit and leak-free seal.
  • Brushed 304 SS Construction: These headers are constructed of durable CNC mandrel bent, brushed, 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.

Air Pump/EGR Block-Off Plate with Gasket 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.

Active Autowerke Performance catless Headers with High Flow Catted Section 1 Pipes - E46 M3

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.

E46 M3 Factory Euro Header Set 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.

E46 325/330i/ci/ZHP Supersprint Tubolare Performance Headers As Used on Project E46 330
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.

E46 M3 Factory Euro Header Set

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.

Active Autowerke Header Set - E46 M3

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
  • Two year warranty

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.

Fits the E46 BMW M3.

E46 M3 Supersprint Cat-Delete Pipes (Deletes Cats In Stock Manifold)

Free ground shipping!

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.

E36 M52/S52 Air Pump/EGR Block-Off Plates Deleting the secondary air pump from your exhaust? Or updating your M50/S50US with the M52 header manifolds? 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). 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.

E46 M3, MZ3 S54, Z4 M Supersprint Tubolare V1 Performance Headers

Free ground shipping! 

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. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and deforming (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. 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 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.

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

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.

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.

E46 M3 AFe Twisted Steel Stainless Performance Headers With Sport Cats

aFe Power's Twisted Steel catted headers deliver 15hp and 14lbs. ft. torque while outflowing the factory cats. These headers use 400cpsi sport cats in place of the factory cats in the headers. aFe's headers outflow the stock cats and manifolds thanks to optimized primary lengths, oversized tubing, and a precison-made 3-1 merge collector for each bank. These headers are crafted in California using TIG-welding, smooth mandrel-bent tubing, and increased pipe diameters. State of the art design removes restriction and keeps exhaust gas flowing smoothly for improved performance and durability. All components are supplied for a hassle-free installation with no modifications necessary.

Features:

  • 400cpsi sport cats
  • Tig-Welded: 100% TIG-Welded by certified craftsmen for race proven strength and durability. TIG-Welding provides the strongest welds reducing stress cracks.
  • Retain Factory Sensors: aFe has designed this system to retain all your factory sensors for a hassle free installation.
  • Mitered Collectors: Mitered collectors not only extend the tube lengths and decrease turbulence, but provide optimal exhaust scavenging. The result is increased horsepower, torque and improved throttle response.
  • CNC Machined Flanges: Flanges are CNC machined not only to be visually appealing but for a precise fit and leak-free seal.
  • Brushed 304 SS Construction: These headers are constructed of durable CNC mandrel bent, brushed, 304 stainless steel tubing for maximum performance, corrosion resistance and strength eliminating cracking.

American Racing Headers - Performance Long tube Header - E46 M3 S54

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. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.
