The oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. 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. 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.

These Wagner downpipes are built with a sport cat to keep the exhaust cleaner.Special software, or stand-alone engine management, may 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

On modern sport sedans and coupes, backpressure management and acoustic tuning are critical to the driving experience.

When your original unit gives out under the stress of high thermal cycles, Turner Motorsport has you covered with this precision replacement from URO Parts.

As exhaust gases exit the N20 engines and flow into an AWE Tuning 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, the exhaust also controls 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.

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. Dyno (M135i): +28hp / +17ft-lbs Supersprint downpipe with sport cat section 1, section 2 straight pipes performance muffler ​This product modifies (but does not remove or defeat) emissions equipment.

FITMENT NOTE: For G-Chassis models (G20, G22), the cutoff build date of 08/2020 is important as cars produced after that date have a downpipe with different bracket locations. Cars with a build date of 08/2020 and earlier have the brackets in a V configuration. Cars with a build date of 09/2020 and later have the brackets in a straight line and require Active Autowerke p/n 11-065G

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 oxygen sensor is part of your BMW's emissions control system and feeds data to BMW engine management computer. The oxygen sensor is positioned in the exhaust pipe and can detect rich and lean mixtures. 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. 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.
