C8 Corvette Corsa Exhaust - 21108 Sport Cat-Back with Mufflers for the C8 Corvette Stingray
The CORSA Sport Cat-Back Exhaust, part 21108, 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. It is CORSA's Sport sound level. Everything from the catalytic converters back gets replaced, and the mufflers stay in the car.
This is the CORSA C8 cat-back that keeps its mufflers, and that is the whole design of it. It is still a full 3.0 inch system, so what changes is the path the gas takes to the back of the car, not whether there is any silencing left in it. 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
- 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
- 4.5 inch Pro-Series tips fill the C8 rear fascia openings rather than sitting back inside them
- Covered for as long as you own the Corvette
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.
