The Project Gamma Axle Exhaust system for the BMW G80 M3 and G82/G83 M4 models drastically improves the vehicle’s exhaust note and enhances performance by featuring a performance muffler that reduces the restricted exhaust flow. The valved design allows for the use of the factory valves and retains all valved features.
