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 Factory Bezels | 2024-2025 Silverado Sierra, Denali 6.2L 157WB (21034-1), listed to fit the 2024-2025 GMC Sierra 1500 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 $1664.99, and the fitment above is what the listing itself states, not a guess.
