Precision-engineered for true BMW enthusiasts, the Active Autowerke E9X M3 Signature Rear Exhaust Gen. 2 delivers the perfect balance of power, tone, and refinement. Constructed from 100% 304 brushed stainless steel, this system embodies performance and craftsmanship with a weight advantage and acoustic design that set it apart.
Featuring large 3-inch mandrel-bent piping, the Gen. 2 Signature Exhaust dramatically improves exhaust flow while maintaining optimal back pressure for balanced power gains across the entire RPM range. Expect a rich, deep tone under throttle and refined civility during cruising—thanks to Active Autowerke’s dual Noise Cancelling Chambers (NCC), which eliminate unwanted drone without compromising the M3’s natural aggression.
The system retains OEM-style flanges for a 100% bolt-on installation—no cutting, welding, or modifications required. Each unit includes adjustable double-walled 76mm Signature tips with the embossed Active Autowerke logo, allowing for precise fitment with both coupe and sedan configurations and a clean finish even with aftermarket diffusers.
Weighing just 40 lbs compared to the OEM’s 55.1 lbs, the Signature Rear Exhaust offers both performance and weight savings. Backed by a two-year warranty, this system is designed for drivers who demand premium sound, precision engineering, and long-term reliability.
