Flowmaster's American Thunder Axle-back exhaust system for the 2015-2023 Ford Mustang with the 2.3L Ecoboost and 3.7L engines is perfect for the person looking for a moderately aggressive sound level outside of the car while maintaining a mild sound level inside. This bolt-on emissions-legal system for cars features 3.00-inch mandrel-bent inlet pipes flowing into a pair of Super 10 Series mufflers for maximum performance.
