This Outlaw Axle-back exhaust system is specifically designed for the 2018-19 Ford Mustang GT coupe and convertibles with the 5.0L engine and Active Performance Exhaust Option. System features include a pair of race-proven Outlaw mufflers for a very aggressive exterior sound level with a noticeable interior tone and large 3.00-inch mandrel-bent 409S stainless steel tubing for high flow, durability, and longevity. Add to that, a pair of high-quality valves to accommodate the factory exhaust actuators for when you really want to open up the sound. The system is finished off with quad 4.00-inch black ceramic coated stainless steel tips for an aggressive look that demands attention, the same as the sound coming from the Outlaw mufflers. Includes all necessary parts, hardware and detailed instructions for an easy installation you can do at home.
