GMC Yukon Performance Exhaust - Stainless Works - Redline Cat-Back - `15-`20. A purpose-built cat-back for 2015–2020 5.3L Yukon/Tahoe applications that delivers an aggressive Redline sound while controlling in-cabin drone.

Built from 304 stainless steel and TIG welded in Streetsboro, Ohio, this Stainless Works Redline system is engineered specifically for the 5.3L motor. The design uses dual turbo-style mufflers tuned to produce a louder, performance-oriented tone without the cabin drone common with many aftermarket systems. The kit connects to the factory connection point using a Y-pipe and exits at the stock location behind the rear tire, preserving fitment and ground clearance. Polished 4" slash-cut double-wall tips finish the look and resist corrosion.
