GMC Yukon XL Performance Exhaust - Stainless Works - Redline Cat-Back - 2015-2020. This Stainless Works Redline cat-back is designed for the 5.3L Yukon XL and delivers a purposeful, aggressive sound while controlling in-cabin drone.

Built from 304 stainless steel and TIG welded in Streetsboro, Ohio, this cat-back uses dual turbo-style mufflers tuned specifically for the 5.3L engine to maximize tone and volume without excessive vibration. The system connects at the factory connection point, exits at the stock location behind the rear tire, and includes dual 4" polished slash-cut double-wall tips. The design improves exhaust flow and gives a track-inspired note that enthusiasts appreciate while maintaining a factory-fit installation process.
