Black Quad Tip Valved Cat-Back for C8 Corvette Stingray with Factory NPP Exhaust
The Corsa Performance COR21100BLK is the black PVD quad tip version of Corsa's valved cat-back system for the 2020-2022 Chevrolet Corvette C8 Stingray 6.2L LT2 with the factory NPP dual-mode exhaust. Like the polished COR21100, this system integrates directly with the factory NPP valve, delivering amplified and refined LT2 sound in both valve modes while Corsa's RSC Technology keeps drone in check. The four black PVD 3.5-inch Pro-Series tips replace the factory tips with a bolder, blacked-out quad exit appearance. Bolt-on installation with no tune required. If you want the best valved C8 exhaust sound with a black aesthetic, COR21100BLK is the system.

Frequently Asked Questions
What is the COR21100BLK?The COR21100BLK is a Corsa Performance valved cat-back exhaust with black PVD quad 3.5-inch tips for the 2020-2022 Chevrolet Corvette C8 Stingray 6.2L LT2 equipped with the factory NPP dual-mode exhaust. It integrates with the factory NPP valve and uses RSC Technology for drone-free sound in both modes.
How does COR21100BLK differ from COR21100?The two systems are identical in construction, function, and sound. The COR21100BLK has black PVD coated quad tips; the COR21100 has polished stainless quad tips. Choose based on your preferred exterior finish.
Is the COR21100BLK compatible with C8 Corvettes without NPP?No. The COR21100BLK requires the factory NPP dual-mode exhaust valve. For C8 Corvettes without NPP, see the COR21102 or COR21102BLK Xtreme systems.
Will the COR21100BLK black tips hold up to exhaust heat?Yes. Black PVD is engineered for high-temperature exhaust applications and maintains its finish far better than painted or powder-coated alternatives under sustained heat cycles.
Does the COR21100BLK require a tune?No. The COR21100BLK is a direct bolt-on system that retains the factory NPP valve and all emissions hardware. No ECU tune is required.
Does the COR21100BLK work on the C8 Z06?No. The C8 Z06 LT6 engine has different exhaust routing and requires a separate Corsa part number. The COR21100BLK is specific to the C8 Stingray LT2.
What warranty covers the COR21100BLK?Corsa Performance backs the COR21100BLK with a limited lifetime warranty against manufacturing defects in materials and workmanship.
Is the COR21100BLK CARB compliant?No. This system is not CARB compliant and is for off-highway use in California. It is street legal in all other US states.
Installation Instructions
- Safely raise the C8 Corvette on a lift or jack stands and allow the factory exhaust to cool completely.
