BMW M2 (F87) 2016-17'
Akrapoviu010d Sound Kit
Evolution Line (Titanium)
The sound of the superb Evolution Line (Titanium) exhaust system can be further controlled by adding the optional Akrapoviu010d Sound Kit. This easy-to-install option makes it possible for 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.
