Description
The Flowmaster American Thunder Cat-Back Exhaust System is designed for 2007–2008 Chevrolet Tahoe and GMC Yukon models equipped with the 4.8L or 5.3L engine. This system is ideal for drivers seeking an aggressive exterior exhaust tone with a moderate interior sound that remains comfortable for daily driving and conversations inside the cabin.
Constructed from heavy-duty 16-gauge mandrel-bent aluminized steel, this cat-back exhaust system delivers durability, improved exhaust flow, and enhanced performance. A Super 50 Series chambered performance muffler provides a deep, aggressive tone while keeping interior resonance under control. Dual 2.50-inch tailpipes clear the factory spare tire, use factory hanger locations, and exit on the sides behind the rear wheels.
The system is finished with dual 3.00-inch polished 304 stainless steel exhaust tips embossed with the Flowmaster logo for a clean, factory-style appearance. Designed as a direct bolt-on upgrade, it includes all necessary hardware and instructions for an easy at-home installation and is backed by a 3-year limited warranty.
