C8 Corvette Stingray Corsa Cat Back Exhaust Muffler Only (2020-2026)

Description

C8 Corvette Stingray CORSA Xtreme Muffler-Only Cat-Back Exhaust (2020–2026) — 21108

If you want maximum CORSA sound without replacing the full system, the CORSA 21108 muffler-only cat-back is the clean answer. This setup replaces the factory mufflers with CORSA’s Xtreme sound-level mufflers to deliver an aggressive, always-on exhaust note—without relying on factory valves or quiet modes.
