Elevate the driving experience of your BMW E46 M3 with the Untd. Performance Axle-Back Exhaust System. Made from high-quality 304 stainless steel, this axle-back exhaust system is designed to provide an aggressive exhaust note, enhanced performance, and a sleek, modern appearance. Tailored specifically for the E46 M3, this system replaces the restrictive stock exhaust and delivers a significant improvement in exhaust flow, reducing backpressure for a more responsive throttle and better performance at high RPMs.
