Description Fitment Table Shipping information

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.
