GMC Yukon Performance Exhaust - Flowmaster - Cat-Back - Black - 15-20. This Flowmaster Flow FX cat-back adds a refined, purposeful tone and a quality upgrade for your 2015-2020 Yukon with the 5.3L V8.

Constructed from durable 16-gauge 409 stainless steel, the system transitions from a 3.00-inch main pipe to dual 2.50-inch mandrel-bent tails for efficient exhaust flow. It exits on the same side with dual 3.50-inch black stainless tips for a clean, custom look. The Flow FX muffler provides a moderate sound level, and dyno testing shows gains of 7 hp and 7 lb-ft at the rear wheels. Installation is straightforward using factory-style hanger locations, detailed instructions, and the included hardware. Backed by Flowmaster’s Lifetime Limited Warranty.
