The Gibson Black Elite single cat-back exhaust for 2014–2018 GMC Sierra 1500 Denali 5.3L pairs premium looks with a deeper tone. Sound is tuned through a stainless Superflow muffler and 3.5in mandrel-bent piping, capped by a black-finished T-304 rolled slash-cut tip. It offers bolt-on installation, reduced interior drone with an aggressive exhaust note, and a limited lifetime warranty.
