CORSA 21108BLK Valveless 3" Cat-Back Quad 4.5" Black Tips 2020-2025 Corvette C8

Vehicle Fitment

• 2020-2025 Chevrolet Corvette C8 Stingray - 6.2L V8 (LT2) - All Trims and Body Styles
• Compatible with both factory NPP (Dual Mode Exhaust) and non-NPP equipped C8 models

Fitment Notes

• Works on all C8 Stingray configurations - with or without factory NPP exhaust - valve simulators are included for both NPP and AFM to prevent check engine lights
• This is a valveless system - no sound mode control; the exhaust is always in an open, aggressive state regardless of driving mode selected
• No valve relearn sequence required after installation - simulators handle all CEL prevention
• Does NOT fit C8 Z06 or ZR1 - those require separate CORSA part numbers
• Bolt-on installation - no drilling or welding required
• This is the Black PVD tip variant (BLK suffix) - polished version available as 21108; carbon fiber tip variants available as 21108CF and 21108CFBLK

Features

• Valveless design - eliminates factory valve complexity and cost while delivering a permanently open, aggressive exhaust note ideal for heavily modified builds

Product Description

The CORSA Performance 21108BLK is a valveless cat-back exhaust system engineered for the 2020-2025 Chevrolet Corvette C8 Stingray with the 6.2L LT2 V8, compatible with both NPP-equipped and non-NPP models. Where CORSA's active valve systems offer variable sound control at a premium, the 21108BLK takes a different approach: eliminate the valves entirely, bring the maximum sound, and keep things simple. This is the system for drivers who want the C8 always loud - for heavily modified builds, dedicated track cars, and anyone who simply wants an aggressive, always-on exhaust note.

Despite removing the valves, CORSA includes both NPP and AFM valve simulators with the kit, eliminating check engine lights and removing the need for any valve relearn sequence after installation. The patented RSC® (Reflective Sound Cancellation) technology keeps the exhaust drone-free at cruise, even with straight-through mufflers. The system is finished with quad 4.5" dual-wall Black PVD Pro-Series tips for a bold, blacked-out look that complements the C8's wide rear. Bolt-on fitment, all hardware included, and backed by CORSA's Limited Lifetime Warranty.
