This exhaust system consists of a single-central muffler with valves and bigger link pipe tubes with a middle muffler. Crafted entirely from titanium, the Evolution system has a unique sound to complement its substantial increase over a very wide rpm range. In-depth engineering has produced a sound completely different from the stock system, giving a deep and sporty sound - with no unwanted overtones or drone, and also a significant change to the sound with the valves in the open or closed position. It needs no re-programming of the ECU because it doesn't trigger any warning lights. With tailpipes in titanium or carbon, and a handcrafted rear diffuser, all available as optional extras, the BMW Evolution is as beautiful as it is powerful.
