GMC Yukon XL Performance Exhaust - Rear - Stainless Works - Legend Cat-Back with Dual 4" Polished Tips - Polished - 2015-2020. A purpose-built cat-back system tuned for the 5.3L motor, this Stainless Works Legend kit delivers a more aggressive tone and improved flow while remaining suitable for daily driving.

This Legend cat-back replaces the rear section of the factory exhaust with CNC mandrel-bent 3" piping and dual turbo-style mufflers engineered to minimize drone yet produce the signature Legend growl. Built from corrosion-resistant 304 stainless steel and TIG welded at Stainless Works’ facility, the system connects at the factory junction and exits at the stock rear location behind the tire. Polished, double-wall 4" slash-cut tips finish the look and resist road wear. It’s a direct-fit solution for owners who want enhanced sound and exhaust flow without extensive modification.
