The Akrapovič Sound Kit (Valve Controller) lets you take manual control of the exhaust valve behaviour on your BMW M2 (F87) Evolution Line system, switching between a quieter setting for daily driving and a louder, more open setting on demand.

Cockpit-Controlled Sound

A dedicated receiver drives the actuators that open and close the valves at the end of the exhaust system, running its own valve management program — distinct from the car's stock logic — that responds to rpm, gear and drive mode. Installation is straightforward and plug-and-play, and it does not replace or modify the exhaust system itself.
