C8 Corvette Corsa 21100CF NPP Valved Cat-Back Exhaust with Carbon Fiber Tips
The CORSA NPP Valved Cat-Back Exhaust, part 21100CF, 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 carbon fiber tips. 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.
Nothing ahead of the tips changes. The mufflers, the valve assemblies and the NPP wiring are the same as the polished version, so the quiet start and the drive-mode control are untouched, and the 1 decibel below stock is still there on a cold morning. The finish is the whole of the difference between this part number and its siblings, and on this one the finish includes the shape of the tip.

Benefits

- CORSA valve assemblies mate to the stock actuator motors, so the car keeps its sound modes
- Flat cut mouth, a different shape from the slash cut polished and Black PVD tips
- A woven texture at the rear fascia that a painted or plated tip cannot give you
- RSC no-drone design targets the cabin resonance that makes a loud exhaust tiring on a long drive
- Four 4.5 inch carbon fiber tips, one pair per side, filling all four rear fascia openings
About The Carbon Fiber Tips
The carbon tips are flat cut, not slash cut, and that is the part worth knowing before you pick a finish. The polished and Black PVD tips on this system are Pro-Series with an angled mouth; the carbon tip is cut square across, so it reads as a different shape at the fascia before you ever notice the weave. Under the carbon is a dual wall 304 stainless inner cone, and its polished edge is the bright ring at the mouth. Four tips, two per side. The set is also sold on its own as the CORSA 21109CF 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.
