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 the longest and best performance for the price.

This item fits the following BMW Chassis:
E82,E90,E92,E93,F30,F34

Fits BMW Engines including:
N55 - up to 08/2013

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..

Made in the USA.

E9X M3 Supersprint Sport Catalytic Converters with Test Pipes are designed to replace the stock primary and secondary catalytic converters with high flow sport cats. With eliminating one set of cats and enlarging the piping the improved flow will increase performance and throttle response as well as increase sound and reduce weight. The straight-flow cat design allows much better flow than the stock cats, giving a significant horsepower and torque gain and a throaty sound. Removing the very restrictive primary cats results in a 25hp gain!

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.

requires:Supersprint section 2 x-pipe, p/n 980713

material:T304 stainless steel

Fitment Note: These sport cats were designed to be used only with the Supersprint section 2 x-pipe (p/n 980713) and Supersprint rear mufflers. Custom fabrication by an exhaust professional will be required to use these without the Supersprint exhaust sections. These cats include post-cat O2 sensor ports allowing for a complete installation by extending your original post-cat O2 sensors to the new location. Special Race software or module may still be required to keep the SES light and fault codes from appearing.

The Supersprint race mufflers on the E92 M3 greatly amplify the audible sensations coming from the M3 V8. The Race mufflers are a freer-flowing and more aggressive sound than the larger, standard 'street' muffler because they don't need to meet conservative European noise limits. These compact mufflers are louder but specially tuned for greater enjoyment of that V8 sound! Supersprint still tunes their exhaust to sound very 'high tech' and less throaty and rumble than typical American exhaust systems.
