The optional Akrapovič Sound Kit for 2024+ BMW X5M/X6M lets drivers control exhaust valve positions from the cockpit, switching between quieter and sportier modes via remote or smartphone app. The kit uses a receiver and actuators to operate the valves; note that using the Sound Kit will invalidate ECE type approval for the affected systems.
