C8 Corvette Stingray Corsa Valve Delete Cat Back Exhaust 21104BLK

CORSA 21104BLK Valve Delete Cat-Back Exhaust with Black PVD Tips for the C8 Corvette Stingray

Full volume from the first crank, finished in black: the CORSA 21104BLK valve delete cat-back exhaust puts a 3.0 inch path and a custom X-pipe under a 2020-2026 C8 Corvette Stingray, coupe or HTC convertible, built without factory NPP, and ends it in quad 4.5 inch Black PVD slash cut tips. The mufflers leave, the AFM valve leaves with them, and what stays is the loudest configuration in the CORSA C8 line for this car, 13 decibels over stock at all times.

Deleting the AFM valve commits the car to one voice, and it is the big one. The 3.0 inch cat-back flows through a custom X-pipe worth 18 horsepower and 16 lb-ft on CORSA's dyno, and with the valve and muffler hardware gone the full system takes 27 pounds off the back of a mid-engine car, two pounds more than the valved version sheds. The quad tips are dual wall 304 stainless in Black PVD, slash cut, and the dual wall construction keeps the outer wall of each tip cooler than a single wall tip, so the finish holds up.

About The Black PVD Tips

The tips are the one choice on this system you make for looks alone. Four 4.5 inch Pro-Series tips, dual wall 304 stainless, slash cut, two per side, finished in Black PVD. Against a dark fascia or dark wheels, the black tips sit into the back of the car and carry the line of it. Dual wall construction keeps the outer wall of each tip cooler than a single wall tip, so the finish holds up. And if your taste changes later, the tips unbolt from the system on their own, without touching the rest of it.

Important Exhaust Notes

• Confirm your RPO NPP status before ordering. This system fits a Stingray that left the factory without NPP. These parts do not fit a 2021 or later car equipped with NPP from the factory, and fitting one there will set a check engine light. Send us the VIN and we will check yours before you order.
• Keep the factory valve actuator motors with the car. The ECU expects valve feedback after the AFM valve is deleted, so the actuators are retained on their brackets or electronically simulated at install. Handled at install, the dash stays clean; skipped, a check engine light follows.
• One volume, all the time. The AFM valve is the hardware that softened 4-cylinder cruise; with it deleted, light resonance can be present in 4-cylinder economy mode, and RSC no-drone technology is not in this configuration.
• Professional installation is the recommended route. Because of GM factory tolerances, some C8 Corvettes need the GM valve relearn sequence afterwards, GM Document ID 5406413; have your installer run it if a check engine light appears.
• This is a bolt-up system: it installs at the factory hangers and mounting locations with the hardware supplied in the kit.
