The Akrapovič Evolution Line system takes exhaust tuning to the next level. Featuring mufflers and link-pipes made from high-grade titanium to dramatically reduce the overall weight, the system provides more power, lowers back pressure, enhances throttle response, and increases torque. With four valves, the first pair operates in four-cylinder mode and the second set comes into action following the driver’s specifications. With an electronic device developed by Akrapovič engineers for the five standard GM modes—Weather, Eco, Tour, Sport, and Track—the system is perfectly matched to operate with the car’s drive mode selector. This produces an even greater range of options for the driver to fully experience the amazing sound of the car. The Evolution Line system, with a new X-pipe, provides even greater performance compared to the Slip-On Line system, and provides a pure race-note soundtrack for this stunning engine, with the enhanced sound characteristics of the V8 configuration and without any drone—just pure enjoyment. Four large-diameter carbon fibre tailpipes with titanium inners complete the appearance of the Evolution Line perfectly, making it stand out as something special.
If the Akrapovič Evolution Line system replaces the GM NPP exhaust system, the Evolution Line maintains the valve regulation of the NPP system.
If the Corvette C7 is not equipped with a GM Performance exhaust (NPP exhaust), then the Control Kit (P-HF886) and Valve Actuator Kit (P-HF868) are mandatory. For Corvette C7s with a Performance exhaust (NPP exhaust), neither the Control Kit (P-HF886) nor the Valve Actuator Kit (P-HF868) is needed.

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.
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
Cars equipped with Akrapovič exhaust systems benefit from additional performance and increased responsiveness.
