Aggressive Sound and Real Power for the C8 Corvette
The CORSA 21108BLK Pro-Series cat-back exhaust gives the C8 Corvette a louder, more aggressive exhaust note while cutting nearly 19 pounds from the factory exhaust system. This valveless 3.0 inch system uses Reflective Sound Cancellation to eliminate drone at cruise, so the cabin stays comfortable while the exhaust note stays intoxicating under throttle. Twin 4.5 inch black PVD Pro-Series tips finish off the look, and valve simulators eliminate the factory NPP valve without triggering a check engine light or requiring a valve relearn.
