This American Thunder axle-back exhaust system is constructed from 16-gauge mandrel-bent aluminized steel and includes a pair of specially designed 60 Series™ performance muffler with the sound that goes hand in hand with the performance image of the Mustang. The muffler is finished off with large 4.00-inch polished stainless steel tips to fill out the exhaust cutouts in the rear valance for a muscular appearance that matches the sound. As an American Thunder® system, it delivers a moderate interior tone and exterior sound that is 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. Designed for an easy fit, the system includes all necessary parts and hardware for easy installation. Note: Fits both coupes and convertibles.
