E9X M3 (2008-2013)

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. Learn More
