Please kindly contact us for availability

The optional Akrapovič Sound Kit enables owners of selected Akrapovič car exhausts to control the sound of the system from the cockpit of their machine. 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 new smartphone app (for iOS and Android) to regulate the valves.

With the use of the optional Akrapovič Sound Kit, the ECE type approval is no longer valid.

This Sound Kit is to be used with the Akrapovic BMW Z4 G29 M40i Titanium Exhaust (Slip-On Line) only.
