Akrapovic Valve control BMW M3/M4 F8x

The Akrapovič Sound Kit for the BMW M3/M4 F8x lets you control the sound of the system from the cockpit with the remote button. Using Akrapovič technology, drivers can easily switch between the quiet mode and a sportier sound.

With the use of a receiver to drive the actuators that open or close the valves at the end of the exhaust system, drivers can use the Sound Remote Controller or the smartphone app for Apple and Android to regulate the valves.
