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 (already included in evolution system) 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.
Intended to be installed with the Akrapovic BMW G80 G82 Slip-On Line Titanium Exhaust System OPF GPF (M3, M3 Competition, M4 & M4 Competition) or the Akrapovic S-BM/T/34H BMW G87 M2 Slip-On Line (Titanium).
Please Note: With the use of the optional Akrapovič Sound Kit, the ECE type approval is no longer valid.
