The Control Kit is only mandatory for Corvette C7s without the Performance exhaust (NPP exhaust). Corvette C7s equipped with a GM Performance exhaust (NPP exhaust) do not need the Control Kit (P-HF886).
The Control Kit gives the driver the option to control the Akrapovič rear exhaust valves through the Corvette C7 drive mode selector. Once a simple installation process is completed, the electronic platform will automatically drive the exhaust's rear valves based on the engine speed, gear, and selected drive mode.
