The Active Autowerke G80/G82 rear exhaust was carefully engineered to increase the sound level over the factory M3 and M4 exhaust, while also allowing for optimum flow and resonance by reusing the actuators from the BMW valves. Every effort was made in addressing the overly quiet sound of the stock OEM exhaust while designing an exhaust worthy for an "M" car. We believe our rear exhaust combined with our mid-pipe and catted downpipes offers the best combination of sound and performance versus any other system on the market today. Available for both models, this axle-back exhaust gives your BMW the deep, throaty, growl a car of its caliber should have had from the factory!
