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.
The Evolution performance exhaust system for the BMW is designed to make the performance and workmanship of the Evolution as perfect as it looks. The whole system is designed to give the smoothest flow and the power and torque gains of the BMW with the Evolution system are simply amazing.
