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 fiber 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 C7 Corvette is not equipped with a GM Performance exhaust (NPP exhaust), then the Control Kit (Zip # EX-2236) and Valve Actuator Kit (Zip # EX-2237) are mandatory. For C7 Corvette's with a NPP exhaust, neither is required.
