Akrapovič audio kit for BMW F80 M3 and F82/83 M4 non OPF

Description

The optional Akrapovič Sound Kit allows owners of select Akrapovič exhausts to control the sound of the system from the cockpit of their machine. Thanks to Akrapovič technology, riders can easily switch from quiet mode to a sportier sound. By using a receiver to control the actuators that open or close the valves at the end of the exhaust system, riders can use the Sound Remote Controller or the new smartphone app (for iOS and Android) to regulate the valves. In this case, the ECE homologation is no longer valid.
