BMW M3 Performance Exhaust by AWE Tuning – Track Edition Cat-Back, Diamond Black. Built for 2021–2027 M3, it brings a raw motorsport tone with quad 4.5-inch double-walled slash-cut tips.
This constant valve-open system uses a straight-through dual 3-inch layout and bespoke X-pipe to let the S58 sing. Included valve simulators keep the ECU content while the rear valved muffler is deleted. It’s 50-state compliant, mates to the factory mid-section via adapters, and uses ball-socket joints for quick install. Expect weight savings vs. stock (more with AWE mid-pipes) and gains up to 3 hp/5 lb-ft.
