GMC Sierra Performance Exhaust - Dual Rear Exit - CORSA Performance - Cat Back - `19-`23 is a direct-fit cat-back system engineered for 2019–2023 GMC Sierra/Chevy Silverado 6.2L Crew Cab short bed (147.5"). It delivers a tuned, aggressive exhaust note on acceleration while maintaining a drone-free experience during cruise.

Built with CORSA's Patented Reflective Sound Cancellation® (RSC) technology, this system is designed to improve flow over stock and provide a strong, controlled tone without unwanted cabin drone. The 3.0" dual rear exit (no tips included) uses 304 stainless steel construction for corrosion resistance and durability. It installs with a bolt-on fitment—no welding required—and includes detailed printed instructions with full-color resources available online. Note: does not fit vehicles equipped with the Max Trailer Towing package. Systems are made in the U.S.A. and backed by CORSA's limited lifetime warranty.
