Description
Overview
The Flowmaster Outlaw Axle-back Exhaust System is engineered to transform the sound and presence of your Ford Mustang. Purpose-built for 2015-2023 Mustang coupes and convertibles equipped with the 2.3L EcoBoost or 3.7L engine, this system pairs aggressive exterior sound with a noticeable interior tone, delivering the deep, race-proven character the Outlaw series is known for. It’s a straightforward, high-impact upgrade for drivers who want their Mustang to be heard.
At the heart of the system is a pair of race-proven Outlaw series mufflers, each measuring 10.50 inches in overall length with a center inlet and center outlet configuration and a 3.00-inch outlet diameter. Large 3.00-inch mandrel-bent tubing feeds these mufflers for smooth, high-flow performance, while the dual tail pipe layout finishes the look with purpose.
Key Benefits
Beyond the aggressive exterior sound level, the Outlaw Axle-back is finished with a pair of large 4.00-inch black ceramic coated stainless steel tips featuring an embossed logo. The result is a bold visual statement that complements the equally bold exhaust note. Because the system uses the factory hangers, installation is quick and easy, requiring no permanent modification to your Mustang.
