Gibson 15-18 GMC Yukon XL SLE 5.3L 2.25in Cat-Back Single Exhaust - Black Elite

If you're looking to give your 2015-2018 GMC Yukon XL SLE with the 5.3L engine a more aggressive sound and a boost in performance, this Gibson Black Elite Series cat-back exhaust system is a solid choice. It's designed to replace your factory exhaust from the catalytic converter back, giving your truck a noticeable upgrade in both sound and style.

Gibson builds this system using high-quality T-304 stainless steel tubing that's mandrel-bent to ensure consistent exhaust flow. The heart of the system is Gibson's Superflow CFT muffler, which uses a baffled and chambered design without internal packing to produce a vigorous, deep tone that's still comfortable inside the cabin, minimizing drone. The system is capped off with a stylish rolled slash-cut tip featuring a black ceramic finish, applied using Gibson's exclusive process for added durability and a sharp look. This exhaust is engineered to bolt directly onto your factory hanger locations, making installation straightforward.

This Gibson cat-back system is designed to provide an estimated 10-15 horsepower gain and 15-20 lb-ft of torque, contributing to improved throttle response. It comes with all the necessary hardware for installation, including factory-style hangers, so you can get it fitted without needing extra parts. Gibson backs this exhaust with a limited lifetime warranty on the stainless steel components.
