A cat-back exhaust replaces the pipes and muffler from the catalytic converter to the tip. It changes how the truck sounds and drops a little weight. This one is the CORSA PERFORMANCE Sport / 3.0 in Cat-Back DRE Turndown | 2022-2023 Silverado ZR2, Sierra AT4X 6.2L 147.5WB (21239), listed to fit the 2022-2023 GMC Sierra 1500 AT4X with the 6.2L V8 (L87).
why this one — Cat-backs are a sound and looks upgrade first. Treat any power claim as unproven unless the maker publishes a dyno sheet. Corsa Direct lists it at $1733.99, and the fitment above is what the listing itself states, not a guess.
