GMC Yukon XL Performance Exhaust - Flowmaster American Thunder Cat-Back. Designed for 2001-2006 Yukon XL 1500 with the 5.3L, this dual side-exit system delivers a deep, confident tone and durable stainless construction.

Built around mandrel-bent 16-gauge stainless steel, the system uses a flanged resonator assembly feeding a specially tuned resonator and a Super 50 Series performance muffler. Dual 2.50-inch tailpipes exit behind the rear tires and are finished with twin 4.00-inch polished 304 stainless tips. Expect a moderate exterior note with a mild interior tone. It connects after the factory catalytic converter, reuses factory hanger locations, includes all needed hardware, and carries a Limited Lifetime Warranty. Note: not compatible with the factory auto-leveling option.
