M Performance Exhaust Muffler

This system is designed to provide an increase in engine output, with documented gains of up to 5 horsepower at 6000 RPM. Beyond the power boost, the mufflers refine the exhaust note, delivering a sportier tone that becomes more pronounced at higher RPMs without being overly intrusive. The design aims for a balance between aggressive sound and daily drivability, ensuring a captivating exhaust note that complements the driving experience. This performance exhaust system is specifically designed for the N54 or N55 equipped E92 and E93 335i models. It is compatible with the 2007-2013 E92 BMW 335i, 335is, 335xi, and 335i xDrive Coupes, as well as the 2007-2013 E93 BMW 335i Convertibles. Installation may require two clamps or welding for proper attachment.
