Akrapovič Chevrolet Corvette Stingray/Grand Sport (C7) Evolution Titanium Exhaust System
The Akrapovič Evolution Line system takes exhaust tuning to the next level. Constructed with mufflers and link-pipes made from high-grade titanium, this system significantly reduces overall weight while providing more power, lowering back pressure, enhancing throttle response, and increasing torque. The system features four valves: the first pair operates in four-cylinder mode, and the second pair is activated according to the driver’s specifications. An electronic device, developed by Akrapovič engineers, integrates seamlessly with the car’s drive mode selector to work with the five standard GM modes—Weather, Eco, Tour, Sport, and Track—offering a greater range of options for the driver to fully experience the car’s remarkable sound.
The Evolution Line system, featuring a new X-pipe, offers even greater performance compared to the Slip-On Line system. It delivers a pure race-note soundtrack for the powerful V8 engine, enhancing its sound characteristics without any drone—just pure driving enjoyment. The system is completed with four large-diameter carbon fibre tailpipes with titanium inners, adding a distinctive and special touch to the Evolution Line’s appearance.
Fitment Notes:
- If the Akrapovič Evolution Line system replaces the GM NPP exhaust system, it maintains the valve regulation of the NPP system.
- For Corvette C7s not equipped with a GM Performance exhaust (NPP exhaust), both the Control Kit (P-HF886) and the 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.
IMPORTANT: THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.

In the words of the Vehicle Standards Agency (VCA), type approval provides "confirmation that production and samples of a design will meet specified performance standards".
For emissions components this encompasses noise, emissions and balanced back pressure, which have a strong influence on maintaining engine performance (power), and fuel efficiency. Type approval ensures that an aftermarket component will reach, or exceed the performance standard of the corresponding OE part.
Type-approval then, is a certain guarantee that an end user will receive a product of OE equivalent performance attributes.
Products on the Progressive Parts website that meet this approval will be clearly marked or labelled EC or ECE approved.
