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.

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).
