Akrapovic 14-17 Chevrolet Corvette Stingray (C7) Valve Actuator Kit.
The Valve Actuator Kit is only mandatory for Corvette C7s without a Performance exhaust (NPP exhaust). Corvette C7s equipped with a GM Performance exhaust (NPP exhaust) do not need the Valve Actuator Kit (P-HF868).
It consists of two genuine GM electrical actuators, which operate the NPP valves in the tailpipes.
