The E46 325i 330i BMW Performance exhaust system increases engine output by allowing exhaust gases to exit the vehicle more efficiently. Engine performance is increased by up to 5 horsepower at 6000 RPM, but there's also another benefit. As RPM escalates, so does the exhaust note, creating a racy but never intrusive sound.
