This Flowmaster Outlaw Axle-back exhaust system is specifically designed for the 2018-2023 Ford Mustang GT with the 5.0L engine and Factory Active Performance Exhaust Option. System features include a pair of our race-proven Outlaw Series 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 our 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 304 stainless steel tips for an aggressive look that demands attention, the same as the exhaust note from the Outlaw Series mufflers. Includes all necessary parts, hardware and detailed instructions for an easy installation you can do at home. Covered by our Lifetime Limited Warranty. Note: Fits both coupes and convertibles.
