CORSA's Black Diamond tips feature a PVD coating that gives the exhaust tips a black chrome look but more importantly, the strength to hold up to heat and normal wear and tear.

Note: CORSA C7 Corvette valve-back design attaches behind the factory exhaust AFM valves, utilizing the factory over axle pipes. The pipes must be cut to install the new CORSA exhaust system. New 2.75" mufflers eliminate the factory 2.5 neck down; installation is handled with heavy duty stainless clamps. Detailed instructions are provided for installation.

Since the introduction of RSC (Reflective Sound Cancellation) technology, Zip Corvette has yet to see a manufacturer match CORSA's performance on these four characteristics (+ HP, + Torque, no resonance & great sound). In addition, you will also experience some trailing throttle noise (or burble) on deceleration, so do not be surprised when your audience thinks you are driving a full blown race car.
