"The Active Autowerke M340i/M440i rear exhaust was carefully engineered to eliminate the overly quiet sound of the factory M340i and M440i exhaust, while also allowing for optimum flow and resonance by reusing the actuator from the BMW valve. Every effort was made in addressing the not so appeasing sound of the stock OEM exhaust, but in designing an exhaust worthy for the BMW 'M' badge. We believe our rear exhaust offers the best combination of sound and performance versus other systems 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!" - Active Autowerke
