The Flowmaster Outlaw axle-back exhaust system is specifically designed for the 2018-2022 Ford Mustang GT coupe & convertible w/the 5.0L engine. This bolt-on system is constructed of 3.00-inch mandrel-bent 409S stainless steel tubing flowing into a pair of our race-proven Outlaw mufflers for an aggressive exterior sound w/a noticeable interior sound level. The 3.00-inch tailpipes exit through the factory cutouts in the rear valance & are finished off w/quad 4.00-inch polished stainless steel tips giving your Pony an aggressive look that matches the sound. This axle-back system retains the factory resonator mid-pipe. Check out our optional Scavenger Series No Resonator X-Pipe #817817 for even more sound & power. This Outlaw system is designed for vehicles without active exhaust valves & uses the factory hanger locations for any easy installation you can do at home in about an hour. Includes easy to follow instructions & all necessary hardware needed. Note: Requires cutting the factory mufflers from the mid-pipe for installation.
