The Akrapovič Sound Kit (Valve Controller) lets owners of the BMW M3 (F80) and M4 (F82/F83) control the sound of their Akrapovič exhaust from inside the car, switching between a quiet mode and a sportier sound.

Cockpit-Controlled Sound

A dedicated receiver drives the actuators that open and close the valves at the end of the exhaust system, controlled via the Akrapovič Sound Remote Controller or the smartphone app (iOS and Android). Installation is straightforward and it does not replace or modify the exhaust system itself.
