The Flowmaster® Outlaw Axle-back exhaust system is specifically designed for the 2018-2023 Ford Mustang GT coupes and convertibles with the 5.0L engine. This system features a pair of race-proven Outlaw® Series mufflers for an aggressive exterior sound level with noticeable interior sound. The system utilizes 3.00-inch mandrel-bent 409S stainless steel tubing, utilizes the factory hanger locations for an easy installation, and is finished off with quad 4.00-inch black ceramic coated tips for an aggressive look that matches the attitude of the sound. This axle-back system retains the factory resonator mid-pipe. For more sound and power, check out our Scavenger® Series no resonator X-Pipe kit part #817817. This system is designed for vehicles without active exhaust valves and includes all the necessary parts, hardware and installation instructions.
