The Flowmaster® Outlaw Axle-back Exhaust System is engineered for 2015-2023 Ford Mustang coupes and convertibles with the 2.3L Ecoboost or 3.7L engines. This system delivers a very aggressive exterior sound with a moderate interior tone, using race-proven Outlaw® mufflers.

The system features 2.25-inch inlet connections for an easy fit to the stock mid-pipe, which quickly expand to 3.00-inch mandrel-bent tubing flowing into the dual Outlaw mufflers for maximum sound and performance. Large 4.00-inch polished stainless steel tips provide a bold, muscular appearance. Installation is straightforward using factory hanger locations and includes all necessary hardware. Covered by Flowmaster’s Lifetime Limited Warranty, this axle-back system is designed for enthusiasts who demand aggressive performance sound without compromising usability.
