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 Borla Borla 14-18 Silverado/Sierra 1500 5.3L 2.75"/2.25" Atak Cat-Back (140549), listed to fit the 2014-2018 GMC Sierra 1500 with the 5.3L V8 (L83).

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. JDP Motorsports lists it at $1624.99, and the fitment above is what the listing itself states, not a guess.
