C8 Corvette Corsa Exhaust - 21108BLK Sport Cat-Back with Black PVD Tips for the C8 Corvette Stingray
The CORSA Sport Cat-Back Exhaust, part 21108BLK, is a 3.0 inch cat-back for the 2020-2026 C8 Corvette Stingray with the 6.2L LT2 V8, finished with 4.5 inch Pro-Series tips in Black PVD. It is CORSA's Sport sound level. Everything from the catalytic converters back gets replaced, and the mufflers stay in the car.
The tips are Black PVD, the same Pro-Series tip as the polished 21108 in a dark finish. On a C8 that shows at the rear fascia: a polished tip catches light and pulls the eye to the cutouts, a dark tip sits back into them. Everything ahead of the tips is the same system as the polished 21108. It is valveless, so there is nothing to switch and the tone is the same every time you start it. A Stingray that came with factory NPP gives up its quiet mode when this goes on.

Benefits
- The dark finish is on the tip as it is built, not a coating added over a polished one
- Dark tips sit back into the C8 rear cutouts instead of drawing the eye to them
- Keeps the mufflers, so the silencing stays inside the system instead of coming out of it
- Valve simulators come in the box, so a car that shipped with factory NPP does not throw a light looking for valves that are gone
- Fits whether your Stingray left Bowling Green with NPP or without
Important Exhaust Notes
This system does not retain the factory NPP quiet and loud modes. On a Stingray that came with NPP you give up the mode switching, and the Sport tone is present in every drive mode from then on. The included valve simulators satisfy the electronics; they do not restore the modes.
