For the person who is looking for a true dual Crossmember-Back exhaust system with an moderate to aggressive exhaust tone. With an easy fit in mind, these systems are constructed from 16-gauge mandrel-bent aluminized steel tubing with a built-in H-pipe crossover, a pair of specially selected Super 44 Series performance mufflers for a deep powerful sound. The 2.50-inch mandrel-bent tailpipes feature a slight turndown at the rear bumper and the system includes all hangers and hardware necessary for installation. The American Thunder systems deliver a moderate to aggressive interior and exterior tone and are best suited to the enthusiast who wants their performance to be heard. Like all Flowmaster exhaust systems, the benefits include improved throttle response, power and mileage. All aluminized steel exhaust systems are covered by our 3-year Limited Warranty. If you prefer stainless steel construction with a Lifetime Limited Warranty, check out exhaust system# 817282.
