As used on the Lime Rock M3 Project Car
With the racetrack and the street in mind, this new exhaust system is crafted from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel�. This flow optimized exhaust system reduces exhaust backpressure and allows the M3�s 414 horsepower V8 engine to produce an even more powerful sound. Inconel�s unique qualities allowed engineers to reduce the thickness of the tubing from 1.5mm to 0.8mm. This resulted in a weight reduction of approximately 40%, or about 20 lbs. when compared to the stock exhaust system. Inconel has also proven to be very corrosion resistant and has been used at the highest level of Motorsports. The M Performance Exhaust includes perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. It represents the ultimate in technology and sportiness, accentuating the individual character of the BMW M3. The exhaust was developed using state-of-the art CAD and FEM technology ensuring optimum fit and OEM quality.

BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.

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 is the pre-cat oxygen sensor. This is a OEM replacement part for BMW part # 11787558073 and .

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 a Bosch O2 sensor - also known as a Lambda probe. Bosch is an OEM supplier to BMW.

Position: after the catalytic converter (post-cat).

This item fits the following BMWs:
2008-2013 E90 E92 E93 BMW M3 Sedan, Coupe, Convertible

BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.
