The Flowmaster® Outlaw axle-back exhaust system is specifically designed for the 2018-2020 Ford Mustang GT coupe and convertible with the 5.0L engine. This bolt-on system is constructed of 3.00 in. mandrel-bent 409S stainless steel tubing flowing into a pair of our race-proven Outlaw® mufflers for an aggressive exterior sound with a noticeable interior sound level. The 3.00 in. tailpipes exit through the factory cutouts in the rear valance and are finished off with quad 4.00 in. 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 Resonator delete pipe #817817 for even more sound and power. This Outlaw system is designed for vehicles without active exhaust valves and uses the factory hanger locations for any easy installation you can do at home in about an hour. Includes easy to follow instructions and all necessary hardware needed. Note: Requires cutting the factory mufflers from the mid-pipe for installation.

Features:

  • Large 4.00-inch Polished 304 Stainless Steel Tips
  • Aggressive Race Proven Outlaw Mufflers
  • Dyno-tuned for Maximum Performance
  • Uses the Factory Hanger Locations
  • Full Stainless Steel Construction
