American Thunder Axle Back Exhaust System
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. The system is constructed out of 409S stainless steel for durability, is finished off with large 4.00-inch polished stainless steel tips and is covered by our Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: The sound level of this system is quieted by the factory resonators. Check out our No Resonator X-Pipe and Y-Pipe kits #81107 and #81108, if you desire more sound from your Ecoboost or 3.7L engine.
