Akrapovic Sound Kit - BMW 3 Series G20 | G21 M340i | 4 Series G22 | G23 | G26 M440i

The optional Akrapovic Sound Kit lets you control the sound of a compatible Akrapovic exhaust system from the driver's seat, switching between a quiet mode and a sportier tone at the touch of a button.

A receiver drives the actuators that open and close the exhaust valves, operated with the Sound Remote Controller or the smartphone app.

Please note: this kit is for use with a compatible Akrapovic exhaust system, which is sold separately. The receiver is already included with the Evolution system.

Please note: fitting the Sound Kit invalidates the ECE type approval of the exhaust system.
