GMC Yukon Performance Exhaust - Stainless Works - Long Tube Headers with Y-Pipe - Mill Finish - `15-`20 is a direct-fit header assembly for 5.3L Yukon and Tahoe platforms. These long-tube, catted headers with a Y-pipe are built to improve exhaust flow and give a more aggressive tone while retaining factory connection points.

Designed for 2015–2020 Chevy Tahoe and GMC Yukon 5.3L models, this Stainless Works kit uses precision-formed tubing and high-flow components to optimize scavenging and reduce backpressure without cutting or modifying your factory system. Constructed from 304 stainless steel with a mill finish and TIG-welded joints, the assembly includes 1-7/8" CNC mandrel-bent primary tubes, 3" slip-fit collectors, high-flow catalytic converters and 3" lead pipes that merge into a Y-pipe for an easy factory connection. Components are manufactured in the USA and backed by a lifetime warranty on materials and workmanship.
