C8 Corvette Corsa 21100BLK NPP Valved Cat-Back Exhaust with Black PVD Tips
The CORSA NPP Valved Cat-Back Exhaust, part 21100BLK, is a 3.0 inch cat-back for the 2020-2026 C8 Corvette Stingray that left the factory with the NPP exhaust, finished with quad 4.5 inch Pro-Series tips in Black PVD. It keeps your drive-mode sound control rather than replacing it. It runs 9 decibels louder than stock at full throttle and 1 decibel quieter with the valves closed.
The tips are Black PVD, the same Pro-Series tip as the polished version in a dark finish. On a C8 that changes how the back of the car reads. A polished tip catches light and pulls your eye straight to the fascia cutouts; a dark tip sits back into them and lets the diffuser be the shape you notice. Nothing ahead of the tips changes, so the quiet start and the drive-mode control are untouched, and the 1 decibel below stock is still there on a cold morning.

Benefits
- Keeps the quiet mode you paid GM for, and adds 9 decibels when you ask for them
- CORSA valve assemblies mate to the stock actuator motors, so the car keeps its sound modes
- 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
- RSC no-drone design targets the cabin resonance that makes a loud exhaust tiring on a long drive
- Four 4.5 inch Pro-Series tips, one pair per side, filling all four rear fascia openings
About The Black PVD Tips
The tips are dual wall 304 stainless, slash cut, finished in Black PVD. Four of them, two per side. The finish is in the tip as it is built rather than painted or wrapped over a polished one, and the durability claim attached to it is the manufacturer's and not ours: per CORSA the Black PVD finish enhances the tip's durability and longevity. What you can judge for yourself is what a dark tip does to the back of a C8. A polished mouth catches light and pulls your eye to the fascia cutouts; a black one sits into them. The set is also sold on its own as the CORSA 21109BLK quad tip kit, four tips in one assembly, fitting CORSA exhaust systems only.
Important Exhaust Notes
A Check Engine Light is the thing C8 owners ask about most before they buy an exhaust, so here is the direct answer. These valve assemblies mate to your factory actuator motors, and that is what keeps the Check Engine Light off when the valves move. Some C8 installs still want the GM valve relearn afterward because of factory build tolerances, and that procedure is GM Document ID 5406413. Your installer will know it. This system is for a Stingray that came with NPP; if your car does not have it, you want a different CORSA part number and we will point you at it.
