This American Thunder system is a true dual exhaust system featuring large 3.00 in. mandrel-bent aluminized steel tubing with a built-in H-pipe crossover assembly flowing into a pair of Super 40 Series performance mufflers. The mufflers deliver a moderately aggressive exterior sound with a moderate interior tone for enthusiasts who want their performance to be heard. The dual 3.00 in. mandrel-bent tailpipes exit straight out the back under the rear bumper. The kit does not include exhaust tips, allowing you to choose the tips of your choice, or run the pipes as is for a muscular look. Includes all necessary hardware, parts and easy to follow instructions. Like all Flowmaster systems, the benefits include improved throttle response, power, mileage and is covered by our 3-year Limited Warranty.
