The Akrapovic Sound Kit is an optional exhaust valve control accessory, not an exhaust system. It adds electric actuators to the valves in the rear section of a compatible Akrapovic exhaust and drives them from a receiver, so the driver can switch between a quiet setting and a louder sport setting from the cockpit using the Akrapovic Sound Remote Controller. On Evolution Line systems the receiver is already supplied, and the kit works with the electronics already in place. Fitting the Sound Kit invalidates the exhaust system ECE type approval.
