The Akrapovic Sound Kit for 2023+ Mercedes C63 S E Performance lets drivers control exhaust sound from the cockpit. Using Akrapovic valve-actuator technology and a receiver (included with Evolution systems), the Sound Remote Controller switches between quiet and sportier modes and regulates valve positions. Note: fitting the optional Sound Kit voids ECE type approval per the manufacturer.
