The Akrapovi? Slip-On Line system is the first step in exhaust tuning. Crafted from high-grade titanium, which considerably reduces the weight in comparison to the stock system, it has been perfectly designed to fit directly onto the existing link pipes. The system increases power, provides better throttle response, and improves torque, and also conjures up an amazing sound from the naturally-aspirated V8 engine. The Slip-On Line system has four valves, designed for the first pair to operate in four-cylinder mode and the second set to come into action according to the driver’s specifications. The system is developed to be compatible with the car’s drive mode selector, and Akrapovi? engineers have developed an electronic device to drive the exhaust valves for each mode—Weather, Eco, Tour, Sport, and Track—giving the driver an even greater opportunity to enjoy the sound of the Akrapovi? Slip-On Line across the whole spectrum of the car’s performance. It’s topped off by four large-diameter carbon fibre tailpipes with titanium inners, to make the Slip-On clearly recognizable as an exhaust that means business.

If the Akrapovi? Slip-On system replaces the GM NPP exhaust system, the Slip-On 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.
