Corsa 3.0" Cat-Back Exhaust with 4.5" Black Pro-Series Tips (21104BLK-1) - 2020-2026 Corvette C8 6.2L Without Factory NPP
Give your 2020-2026 Chevrolet Corvette C8 6.2L V8 an ultra-aggressive exhaust note with the Corsa 3.0" Cat-Back Exhaust System. Developed for drivers who want to eliminate factory exhaust restrictions, reduce weight, and dramatically increase the sound of the mid-engine C8, this system combines a full 3.0" Cat-Back design with quad 4.5" black Pro-Series tips and an exhaust note rated 13 dB louder than stock.
This 21104BLK-1 configuration is designed for C8 Corvette Coupe and Convertible/HTC models without factory NPP exhaust. The system is engineered around the Corvette's AFM functionality while replacing the factory exhaust components with a freer-flowing, significantly lighter performance exhaust.
Ultra-Aggressive C8 Exhaust Sound
Corsa engineered this Cat-Back specifically for Corvette owners seeking an ultra-aggressive exhaust note. Rated at 13 dB louder than the stock C8 Corvette exhaust, the system delivers a substantial increase in volume designed to let the naturally aspirated 6.2L V8 make its presence known.
This configuration is intended for enthusiasts who prioritize an aggressive exhaust experience rather than a restrained factory-like sound. The performance-oriented Cat-Back is designed to eliminate factory exhaust restrictions while delivering the additional sound expected from a C8 exhaust upgrade.
Designed Around the C8's AFM System
The Corsa system is designed around the C8 Corvette's AFM functionality and the unique exhaust characteristics created when the engine enters its 4-cylinder economy mode. Corsa developed its AFM-only C8 Cat-Back exhaust systems to eliminate restrictions, maximize weight savings, and deliver a substantially more aggressive exhaust note while addressing resonance associated with cylinder-deactivation operation.
It is important to note that this system does not contain Corsa Performance No Drone RSC Technology. Corsa also states that 4-cylinder mode may still exhibit light resonant frequencies.
13 dB Louder Than Stock
Corsa rates the 21104BLK-1 system at 13 dB louder than the stock C8 Corvette exhaust. This significant increase gives the 6.2L V8 a much more aggressive exhaust character and makes the system well suited for owners who want their C8 to deliver considerably more sound than the factory exhaust.
27 LB Weight Savings
The Corsa Cat-Back provides an impressive 27 lb weight savings compared with the factory exhaust components it replaces. Removing nearly 30 lbs from a performance-focused vehicle like the C8 Corvette provides a meaningful benefit in addition to the system's increased sound and reduced exhaust restriction.
The combination of substantial weight reduction and a freer-flowing Cat-Back design makes the 21104BLK-1 a functional performance upgrade as well as an acoustic and visual transformation.
Full 3.0" Cat-Back Exhaust
The system uses a full 3.0" Cat-Back configuration with a dual rear exit layout. Its performance-oriented design is engineered to eliminate factory restrictions and provide a freer-flowing exhaust path for the Corvette's naturally aspirated 6.2L V8.
Corsa combines increased exhaust volume, reduced restriction, and substantial weight savings into a complete Cat-Back package developed specifically around the unique requirements of the mid-engine C8 Corvette.
Quad 4.5" Black Pro-Series Tips
Completing the 21104BLK-1 are quad 4.5" black Pro-Series exhaust tips. The dual rear exit configuration uses twin tips at each exit for a total of four large exhaust outlets at the rear of the Corvette.
Each Pro-Series tip features dual-wall construction and a slash-cut design. The black finish provides a darker and more aggressive appearance than the polished-tip configuration, while the oversized 4.5" outlets give the rear of the C8 a visual presence that matches the system's ultra-aggressive exhaust note.
Professional Installation Recommended
Corsa recommends that installation of this exhaust system be performed by a professional. Due to GM factory tolerances, some C8 Corvette exhaust installations may require the GM valve relearn sequence to mitigate a check engine light.
When required, the valves should be recalibrated according to GM Document ID 5406413. Refer to the Corsa installation instructions for complete installation and valve recalibration details.
Important NPP Compatibility Information
This exhaust is intended for C8 Corvette applications without factory NPP exhaust. Corsa specifically warns that the affected non-NPP exhaust systems are not for use on 2021 and newer vehicles originally equipped with NPP from the factory because installation can cause a check engine light.
Always verify the Corvette's original factory exhaust configuration before ordering. The 21104BLK-1 should be selected only for compatible non-NPP C8 Corvette applications.
