The Flowmaster American Thunder Exhaust System is engineered to improve your vehicle’s performance, efficiency, and sound. Constructed from durable 16-gauge mandrel-bent aluminized steel, it flows into a Super 50™ Series performance muffler for a balanced tone—moderate inside the cabin and outside the vehicle. Dual 2.5-inch mandrel-bent tailpipes use factory hanger locations and offer two exit options: straight out the back under the bumper or out to the sides behind the rear wheels, ideal for towing. Polished 3-inch 304 stainless steel tips complete the look, while all necessary hardware and instructions are included for a quick, easy installation. Backed by Flowmaster’s 3-year limited warranty, it’s a reliable performance upgrade for your vehicle.
