Akrapovic Sound Kit for selected Akrapovic car exhausts, specified for 2020 BMW M340i (G20) and 2021 BMW M440i (G22) applications. The kit lets drivers control exhaust valves from the cockpit, switching between quiet and sportier sound using the Sound Remote Controller and the receiver included with evolution systems. Akrapovic notes that fitting the optional Sound Kit voids ECE type approval and that actuators open or close the end-of-system valves to alter tone.
