Corsa 3.0" Cat-Back Exhaust with Valve & Muffler Delete and 4.5" Black Pro-Series Tips (21105BLK-1) - 2020-2026 Chevrolet Corvette C8 with Factory NPP
Give your 2020-2026 Chevrolet Corvette C8 a significantly more aggressive exhaust note with the Corsa 3.0" Cat-Back Exhaust with Valve & Muffler Delete and black Pro-Series tips. Designed specifically for C8 Corvettes equipped with the factory NPP option, the 21105BLK-1 combines a full 3.0" Cat-Back configuration with a 21 lb weight reduction, an exhaust note rated 13 decibels louder than stock, and quad 4.5" black Pro-Series tips.
This configuration is built for C8 owners looking for a more aggressive approach to the 6.2L LT2 exhaust. The Valve & Muffler Delete design increases sound while removing substantial weight from the factory exhaust system, creating a more direct performance-oriented character backed by Corsa's application-specific C8 engineering.
Valve & Muffler Delete Configuration
The Corsa 21105BLK-1 is specifically identified as the Valve & Muffler Delete configuration for the C8 Corvette. By eliminating the muffler and valve components from this configuration, the system is focused on maximizing exhaust presence and reducing weight compared with the factory system.
The result is one of the more aggressive configurations in this Corsa C8 exhaust family, delivering substantially increased volume from the naturally aspirated 6.2L LT2 while dropping 21 lbs from the stock exhaust.
13 dB Louder Than Stock
Corsa rates the 21105BLK-1 at 13 decibels louder than the factory exhaust. This substantial increase gives the C8's 6.2L LT2 a much more commanding exhaust note and makes this configuration an excellent choice for drivers who prioritize aggressive sound.
Unlike the related 21103 configuration, which is listed with a broader sound range, the 21105BLK-1 is specifically rated at 13 dB louder than stock. Its Valve & Muffler Delete design is focused on delivering increased exhaust volume rather than retaining the quieter characteristics of the factory system.
Bring Out the Sound of the 6.2L LT2
The naturally aspirated 6.2L LT2 is at the heart of the C8 Corvette driving experience, and the 21105BLK-1 allows considerably more of its V8 character to reach the driver. The combination of the 3.0" Cat-Back design and Valve & Muffler Delete configuration produces a more aggressive exhaust presence than the stock system.
For Corvette owners who want the exhaust to become a much more noticeable part of the driving experience, the 13 dB increase provides a dramatic change while maintaining a Cat-Back configuration.
21 LB Weight Savings
The Corsa 21105BLK-1 also provides a substantial reduction in exhaust weight. At 21 lbs lighter than the stock exhaust system, this configuration removes unnecessary mass while simultaneously increasing exhaust volume.
The 21 lb weight savings is especially relevant on a performance platform like the C8 Corvette, where reducing weight complements the vehicle's focus on acceleration, handling, and overall performance.
3.0" Cat-Back Exhaust Design
The Corsa 21105BLK-1 uses a complete 3.0" Cat-Back configuration engineered around the packaging requirements of the mid-engine C8 Corvette. The system features a dual rear exit and retains the Corvette's aggressive center-mounted quad-tip exhaust layout.
This performance-oriented configuration combines 3.0" exhaust piping with the Valve & Muffler Delete design to create the aggressive sound and reduced weight that distinguish the 21105BLK-1 from the factory exhaust.
Quad 4.5" Black Pro-Series Tips
The 21105BLK-1 finishes the rear of the Corvette with four large 4.5" black Corsa Pro-Series exhaust tips. Twin tips are positioned at each rear exit, maintaining the signature quad-tip appearance of the C8 while adding a darker and more aggressive visual presence.
The Pro-Series tips feature dual-wall construction with a slash-cut profile. The black finish gives the system a stealthier appearance than the polished 21105-1 configuration while complementing the C8's rear diffuser and performance-focused styling.
Developed for Factory NPP C8 Applications
The Corsa 21105BLK-1 is intended for 2020-2026 Chevrolet Corvette C8 models originally equipped with the Factory NPP option. Correct factory exhaust configuration is important when selecting a Corsa C8 system because Corsa offers different exhaust designs for NPP and non-NPP applications.
Corsa's broader NPP C8 exhaust development includes exclusive cast AFM and NPP valve assemblies designed around the intense heat requirements of the mid-engine Corvette and engineered to bolt directly to factory actuator motors. This specific 21105BLK-1 product, however, is identified as the Valve & Muffler Delete configuration.
Important RSC Technology Notice
Although Corsa's general C8 NPP exhaust information references its advanced RSC No Drone Technology, the specific application information supplied for part number 21105BLK explicitly states that this system does NOT contain Corsa Performance No Drone RSC Technology.
The part-specific information takes precedence for the 21105BLK-1. This system should not be represented as containing Corsa's No Drone RSC Technology.
4-Cylinder Mode Resonance
Corsa notes that 4-cylinder mode may exhibit light resonant frequencies on the affected 21105BLK exhaust configuration. This is an important characteristic to consider for drivers who regularly operate their C8 in 4-cylinder economy mode.
Drivers choosing the 21105BLK-1 should do so for its aggressive 13 dB increase in sound, 21 lb weight reduction, Valve & Muffler Delete configuration, and black Pro-Series styling rather than expecting the resonance-control characteristics associated with Corsa RSC-equipped exhaust systems.
Professional Installation Recommended
Corsa recommends that installation of its C8 Corvette exhaust systems be performed by a professional. Proper installation is especially important on the C8 due to the vehicle's exhaust control system and the possibility that a GM valve relearn procedure may be required.
GM Valve Relearn May Be Required
Due to GM factory tolerances, some C8 exhaust systems may require a GM valve relearn sequence following installation 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 information and additional details regarding the GM valve relearn procedure.
