Expert's advice:
"The sound of the superb Evolution Line (Titanium) exhaust system can be further controlled by adding the optional Akrapovič Sound Kit. This easy-to-install option makes possible louder or quieter settings of the Evolution Line. It has a special program for valve management (in quiet and loud mode) that is different from the stock version and controls the valves according to rpm, gear, and car mode."
The Akrapovic Exhaust systems are tested and race proven by several BMW teams including the BMW M Team RLL & BMW M Motorsport Team competing in IMSA & WEC respectively. Racing at the limit for 6, 12 or even 24 hours continuously, these exhaust systems are put to the ultimate test.
