The Flowmaster® American Thunder® Cat-back exhaust system is designed for 2015-2017 Ford Mustang GT 5.0L coupes and is perfect for the person looking for an aggressive sound level outside of the car, while maintaining a moderate sound level inside the car. This bolt-on emissions-legal system features our exclusive dual 3.00 in. mandrel-bent Scavenger Series® X-pipe assembly for maximum power and a deep unique tone. The Scavenger X-pipe exits into a pair of specially designed 60 Series™ performance mufflers with 3.00 in. mandrel-bent tailpipes and are finished off with large 4.00 in. polished stainless steel tips. Designed for an easy fit, this system uses the factory hanger locations and includes all necessary parts and hardware for an installation you can do at home. Note: Does not fit Convertibles.
