Akrapovic Valve control
The optional Akrapovic Sound Kit enables owners of selected Akrapovic
car exhausts to control the sound of the system from the cockpit of
their machine. Using Akrapovic technology, drivers can easily switch
between the quiet mode and a sportier sound. With the use of a receiver
to drive the actuators that open or close the valves at the end of the
exhaust system, drivers can use the Sound Remote Controller or the new
smartphone app (for iOS and Android) to regulate the valves.
