C8 Corvette Stingray Corsa Xtreme Exhaust – No Valves (2020-2026)

Description

C8 Corvette Stingray Corsa Xtreme Muffler Delete Exhaust – 21105 / 21105BLK / 21105CF

Upgrade your 2020–2026 C8 Corvette Stingray with the Corsa Xtreme Muffler Delete Exhaust System (21105 series) for maximum volume, aggressive tone, and race-inspired performance. This system is designed for owners who want constant, full-open exhaust sound with no quiet mode and zero restriction.

The 21105 system is a true muffler-delete cat-back exhaust. Because the mufflers are eliminated entirely, exhaust flow is always open, delivering Corsa’s loudest Xtreme Sound Level at all times. There is no sound change between drive modes.

To maintain ECU compliance on vehicles originally equipped with factory valves, CORSA reuses the OEM NPP valve motors mounted on supplied brackets. These motors continue to cycle electronically, preventing warning lights, but they do not control exhaust sound.

Constructed from 3.0-inch T304 stainless steel, this system reduces weight, increases exhaust flow, and features CORSA’s RSC® No Drone Technology to eliminate interior resonance at cruising speeds—even with an aggressive exterior tone.
