BMW G82 Performance Exhaust - Akrapovic - Sound Kit (2021–2027). Take command of your M4’s Akrapovic valve-controlled exhaust from the driver’s seat with this plug-in kit.

Engineered by Akrapovic for select valve-equipped systems, the Sound Kit adds an in-cabin way to switch between a subdued tone and a more aggressive soundtrack. A dedicated receiver manages the actuators that open and close the tailpipe valves, while the handheld remote lets you toggle modes whenever you want. When used, the ECE type approval of the exhaust is no longer valid. Built for the G82 M4 and commonly shared across G8x platforms; please verify compatibility with your specific Akrapovic system before ordering. Images shown are for reference.
