The BMW M4 Performance Exhaust by AWE Tuning, specifically the Cat Back Track Edition in Diamond Black for models `14-`20, is designed for those who crave an intensely bold exhaust note. This exhaust system is tailored to bring out the rich and dynamic tones of your BMW M4, ensuring both a boost in performance and an auditory experience that's impossible to ignore.

Crafted meticulously from U.S.-sourced .065" wall T304L stainless steel, this exhaust system offers unparalleled durability and performance. The absence of a valved muffler promises a consistently open valve experience, resulting in a more spirited driving sound at all times. The system provides a weight reduction of 22.5 lbs and ensures max performance gains of 12 hp and 16 lb-ft of torque at the wheels. With its precision-engineered X-pipe, the exhaust delivers a distinct S55 engine tone with or without the OPF regulations, making it legal in all 50 states.
