Description
The Flowmaster American Thunder Axle-Back Exhaust System is designed for 2015-2023 Ford Mustang models equipped with the 2.3L EcoBoost or 3.7L engine. This system delivers an aggressive to moderate exterior exhaust tone while maintaining a mild and comfortable sound level inside the cabin.
This emissions-legal, bolt-on axle-back system features 3.00-inch mandrel-bent inlet pipes that flow into a pair of race-proven Super 10 Series chambered mufflers, delivering maximum performance and Flowmaster’s signature sound. Constructed from durable 409 stainless steel, the system is finished with large 4.00-inch polished stainless steel exhaust tips for an aggressive, performance-focused appearance.
Designed for a precise fit, this system uses the factory hanger locations and includes all required hardware for a straightforward installation. The sound level of this system is quieted by the factory resonators. For customers seeking increased volume, optional no-resonator X-Pipe and Y-Pipe kits are available for the 2.3L EcoBoost and 3.7L engines. Backed by Flowmaster quality and a Lifetime Limited Warranty, this exhaust system is engineered for performance, durability, and sound control.
