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 Pacific Performance Engineering 2014-2018 GM Silverado/Sierra 1500 4.3L/5.3L Cat-Back Exhaust System - Single Exit, 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. PPE Direct lists it at $549.99, and the fitment above is what the listing itself states, not a guess.
