Corsa 3.0" Cat-Back Exhaust with 4.5" Carbon Fiber Black Tips (21104CFBLK-1) - 2020-2026 Corvette C8 6.2L Without Factory NPP
Transform the sound, performance, weight, and appearance of your 2020-2026 Chevrolet Corvette C8 with the Corsa 3.0" Cat-Back Exhaust System. Designed for C8 owners seeking an ultra-aggressive exhaust note, the 21104CFBLK-1 combines a freer-flowing 3.0" exhaust, AFM-specific engineering, dyno-proven performance gains, substantial weight savings, and quad 4.5" carbon fiber black tips.
Each system has been track-tested and dyno proven to maximize performance, producing gains of up to 18 horsepower and 16 lb-ft of torque while shaving 25 lbs from the stock exhaust system. With an exhaust note rated 13 dB louder than stock, this system is built for drivers who want the C8's naturally aspirated 6.2L V8 to deliver a considerably more aggressive sound.
Ultra-Aggressive C8 Exhaust Sound
Corsa developed this exhaust for drivers seeking an ultra-aggressive exhaust note from the C8 Corvette. Rated at 13 dB louder than stock, the 21104CFBLK-1 provides a substantial increase in exhaust volume to better showcase the sound of the mid-engine 6.2L V8.
The system is engineered to eliminate factory exhaust restrictions, maximize weight savings, and bring significantly more exhaust sound while addressing the unique exhaust characteristics associated with the Corvette's 4-cylinder economy mode.
Up to 18 Horsepower and 16 LB-FT of Torque
The Corsa 21104CFBLK-1 is more than a sound and appearance upgrade. Each system has been track-tested and dyno proven to maximize performance, producing gains of up to 18 horsepower and 16 lb-ft of torque.
These measurable performance gains complement the freer-flowing Cat-Back design, making the system a performance-focused upgrade for C8 owners who want improved output along with a substantially more aggressive exhaust note.
25 LB Weight Savings
Corsa also engineered the system to reduce unnecessary exhaust weight. The 21104CFBLK-1 shaves 25 lbs from the stock exhaust system, providing a significant reduction while simultaneously improving performance and sound.
Combining a 25 lb weight savings with gains of up to 18 horsepower and 16 lb-ft of torque gives this Cat-Back multiple performance benefits beyond its aggressive exhaust note and carbon fiber tip appearance.
Designed Around the C8's AFM System
Corsa's AFM-only C8 Cat-Back exhaust system is engineered around the unique challenges created by the Corvette's cylinder-deactivation system. When the engine enters its 4-cylinder economy mode, the change in engine operation can create different exhaust frequencies than those produced during normal V8 operation.
Corsa designed this system to eliminate exhaust restrictions, maximize weight savings, and deliver an aggressive exhaust note while addressing resonance associated with 4-cylinder operation. However, Corsa specifically notes that this system does not contain Corsa Performance No Drone RSC Technology and that 4-cylinder mode may still exhibit light resonant frequencies.
3.0" Cat-Back Exhaust System
The 21104CFBLK-1 uses a 3.0" Cat-Back configuration with a dual rear exit layout. The performance-oriented exhaust design replaces the factory Cat-Back components with a system engineered to reduce restriction and maximize the performance potential of the C8 Corvette's 6.2L V8.
Its combination of increased exhaust sound, dyno-proven horsepower and torque gains, and substantial weight reduction makes the system a comprehensive performance upgrade rather than simply an exhaust tip or muffler change.
Quad 4.5" Carbon Fiber Black Tips
The 21104CFBLK-1 is finished with quad 4.5" carbon fiber exhaust tips featuring black accents. The dual rear exit layout uses twin tips at each exit for a total of four large outlets across the rear of the C8.
The carbon fiber tips feature dual-wall, straight-cut construction, giving the Corvette a premium motorsports-inspired appearance that complements the C8's mid-engine design. The black detailing provides a darker alternative to the polished carbon fiber configuration and pairs especially well with the ultra-aggressive character of this exhaust system.
Track-Tested and Dyno Proven
Corsa states that each system has been track-tested and dyno proven to maximize performance. The resulting combination delivers up to 18 additional horsepower, 16 lb-ft of additional torque, and a 25 lb reduction compared with the stock exhaust system.
For drivers using their C8 as a performance-focused street car or enjoying it in more demanding driving environments, the 21104CFBLK-1 combines measurable performance improvements with a significantly more aggressive exhaust experience.
Professional Installation Recommended
Corsa recommends that installation of the exhaust be performed by a professional. Due to GM factory tolerances, some C8 Corvette exhaust systems may require a GM valve relearn sequence to mitigate a check engine light.
When a relearn is required, the valves should be recalibrated according to GM Document ID 5406413. Refer to the Corsa installation instructions for complete installation information and additional details regarding the valve recalibration procedure.
Important NPP Compatibility Information
This system is intended for compatible C8 Corvette applications without factory NPP exhaust. Corsa warns that specified non-NPP exhaust systems are not for use on applicable 2021 and newer Corvettes equipped with NPP from the factory because an incompatible exhaust configuration can cause a check engine light.
Always verify the Corvette's original factory exhaust configuration before ordering to ensure the correct Corsa system is selected.
