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.

Designed for an easy fit, the system includes all necessary parts and hardware for easy installation. Note: Fits both coupes and convertibles.
