A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for BMW's with the N20 and N26 motors. This sensor is mounted in the catalytic converter in the rear most position. OEM replacement for BMW # 11787589122.

A larger down pipe relieves some of this pressure, resulting in quicker and more efficient spool. With Active Autowerke's Signature downpipe, your N20 can rev quicker, and deliver more horsepower and torque. Minimizing back pressure while remaining daily drive-ability was the goal of our N20 downpipe. Owners can now upgrade to a product that is affordable, reliable, and easy to install. After months of research and development, our engineers settled on a 3.5 diameter pipe which utilizes the least number of bends possible. However, the Signature N20 down pipe still fits easily into the OEM location, with a painless installation process. Constructed entirely from 304 stainless steel with 1.5MM wall thickness, we are confident that you'll be pleased with how robust and durable this down pipe is. Trouble-free installation and a long lifespan ensure that you'll enjoy many miles of performance with your N20!

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the longest and best performance for the price. This is the OEM Bosch oxygen sensor for BMWs with B46, B48, and N74 engines. Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

This front section is a direct replacement for the stock 235i/335/435/M2 exhaust with one key difference - the Supersprint uses full 80mm piping for improved flow out of the turbo. One of the best and easiest ways of getting more power from a stock turbo is by helping it push exhaust gas and larger and smoother exhaust piping will help with that. Where the stock system is bent and crimped, the Supersprint is a full 80mm along its entire length. This section 1 will fit to the stock or Supersprint turbo downpipe and a stock or Supersprint section 2 exhaust.

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!

This item fits the following BMWs:

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

As exhaust gases exit the 340i / 440i engine and flow into an AWE 180 Technology equipped resonator, they pass through strategically located ports and into reflection chambers. Sound waves, carried by these exhaust gasses, bounce off the walls of the reflection chambers. By controlling the size and location of the ports and the chambers, we also control when the sound waves exit the chambers. The specific timing of when the reflected sound waves rejoin the main exhaust flow creates a one-hundred-and-eighty-degree out-of-phase sound wave that cancels out problematic frequencies. Features: Straight-through design featuring AWE's proprietary drone-canceling solution Full 3" CNC mandrel-bent system Max gains of 9 hp and 11 ft-lbs of torque at the crank Axle-back design for the street Performance Mid Pipe for racing applications Tip options include 90 or 102mm double-walled tips in chrome silver or diamond black Handcrafted, CNC mandrel-bent 2.5” U.S.-sourced T304L stainless steel Engineered, designed, and manufactured in house at AWE No check engine light - guaranteed Perfect fitment - guaranteed AWE Lifetime Warranty Whats included: Axle-back exhaust Two exhaust tips All necessary hardware

This oversized front (section 1) pipe is a direct replacement for the stock exhaust section. It's been optimized for flow with 80mm tubing and mandrel bends. It does have compressed sections like on the stock piece. Although this is very similar to the factory exhaust pipe the larger size from the Supersprint provides better flow and less restriction (key for making power in turbocharged engines).

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.

The Active Autowerke BMW F30 328I signature exhaust is located in a class all of its own. This product is a must for any enthusiast searching for true performance, added durability and an attractive weight advantage when it comes to the F30 328I performance signature exhaust.

This system is constructed from 100% polished 304-stainless steel and features adjustable 80 mm double walled tips, making it ideal both for two-door and four-door models (which also allows for cleaner fitment with diffusers).

This BMW F30 exhaust delivers everything we know you would want in a performance exhaust: eye-catching style, a sophisticated yet aggressive tone, weight savings, and – most importantly – measurable horsepower performance gains!

This muffler turns your 328I exhaust tone into a sporty but mellow tone that is not only exhilarating but non obtrusive on your ears.

The factory counterpart weighs 29 lbs. while the Active Autowerke Signature exhaust weighs only a mere 19 lbs. Weight savings are not the only attributes, this 328I performance exhaust has a modular design with its v-band clamps that makes fitment a snap. A revelation in BMW tuning.

On the in-house Active Autowerke Mustang dyno, their otherwise 100% stock 2013 328I test mule spun the rollers to the tune of an extra 9 RWHP, and 13 LB-FT of torque…from “just” a quality muffler upgrade.

Turbos love to exhale, and we are very anxious to continue to unearth just how much extra power is hiding in the stock exhaust system.

FEATURES:

  • Larger diameter mandrel bent piping for maximum flow
  • Durable, polished 100% 304 stainless steel
  • Double-walled 80 mm signature stainless tips
  • Adjustable tips with embossed Active Autowerke logo on the dual tip model
  • Improved power & torque throughout entire RPM band
  • Actual dyno measure results with gains of 10 + WHP over stock configuration
  • Weighs 19 lbs. vs. the factory of 29 lbs.
  • Fitment for coupe, convertible and sedans
  • Complete illustrated instruction manual
  • Two year limited warranty included

NOTE:

  • Exhaust system requires cutting of the factory pipe for installation. Dimensions and cutting measurements are included in the instructions.

 

Fits F30 BMW 228i and 328i models with the N20 engine.

This Supersprint center section will delete the secondary silencer/resonator in the stock exhaust and fit with the Supersprint sport rear muffler. The front of this section is clamped to the stock secondary cats via a set of connecting pipes. By eliminating the resonator, and matching it to the rear muffler, more engine sound can be heard. And with less restriction more torque and horsepower can be released.

True BMW performance, durability, and attractive weight advantages with innovative features place the Active Autowerke BMW F3x 335i exhaust in a class of its own. And now Active Autowerke has developed Gen 2 of this model which has been enhanced to take advantage of the OEM valve system. This system is constructed from 100% Brushed 304-stainless steel and features adjustable brushed Active Autowerke double-walled tips. And now the improved sound becomes more pronounced when the valve is opened by the ECU. Rather than creating a complete exhaust system, Active Autowerke opted for a compact design built in a smaller package to deliver more value. The Active Autowerke F3x 335i Gen 2 BMW Rear Exhaust System provides an increase in horsepower, better sound and appearance making it the choice for the avid BMW enthusiast. The system is a straight-through design providing substantial improvements to gas flow over the factory exhaust. Our innovative muffler can design provides maximum volume with the exhaust valve open for a true sport sound. This exhaust delivers a wide-open sound, a solid 15+hp boost and key gains in the midrange with the valve open while the sound comes out nonintrusive with a rich mellow tone with the valve closed. Just like replacing the BMW factory rear exhaust, the Active Autowerke BMW Performance rear exhaust does it in much the same way, if not better by using a much beefier, heavy-duty TORCA style exhaust clamp. TORCA clamps are known for their strength and sealing capabilities to make that tight seal. Other features like height-adjustable mounting tabs make this exhaust easy to install. Key Features: Large mandrel bent piping for maximum flow Uses factory valve system for maximum exhaust sound Durable, Brushed 100% 304 stainless steel for durability Double-walled signature brushed, black or carbon stainless tips Adjustable Tips with Embossed Active Autowerke Logo Improved power & torque throughout entire RPM band Gains of 12-15 HP over stock configuration Tight seal with use of TORCA style exhaust clamps Height adjustable mounting brackets make installation easy Factory curb weight 27.0 Lbs, Active 335i weighs 22.0 Lbs Fitment for Coupe, Convertible and Sedans Complete illustrated instruction manual Two-year warranty Applications: BMW F30 335i, xi (Sedan) BMW F32 435i, xi (Coupe) BMW F33 435i, xi (Convertible) BMW F36 435i (Coupe)

Want to install a downpipe on your B58 equipped BMW, but still need to pass emissions? Evolution Racewerks has the answer for you with their B58 Catted downpipe. The Evolution Racewerks Competition Series Catless Downpipes is constructed from 304 stainless steel, featuring mandrel bent piping.  These are 100% TIG welded by in house fabricators and built in the USA! 

The factory turbocharger turbine housing utilizes a V-Band flange which has been duplicated and CNC machined cut out of billet 304 stainless steel. Stainless Steel CNC machined O2 sensor and laser cut brackets are TIG welded using stainless steel rods. The O2 sensor remains positioned at the factory location. Also, since Evolution Racewerks uses a larger 4.5" pipe right after the turbocharger, turbo backpressure is significantly reduced, resulting in less exhaust turbulence and backpressure which again improves throttle response and decreasing turbo lag.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. This is the OEM oxygen sensor for BMWs with B46, B48, and N74 engines. As a leading source of high-performance BMW parts and accessories since 1993, we at Turner Motorsport are honored to be the go-to supplier for tens of thousands of enthusiasts the world over. With over two decades of parts, service, and racing experience under our belt, we provide only quality performance and replacement parts. All of our performance parts are those we would (and do!) install and run on our own cars, as well as replacement parts that are Genuine BMW or from OEM manufacturers. We only offer parts we know you can trust to perform!

The goal of the oxygen sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution.
