The Flowmaster Outlaw® Cat-back exhaust system is designed for 2018-2020 Ford Mustang GT 5.0L with the Factory Performance Active Exhaust option, and is perfect for the person looking for a very aggressive exhaust note both inside and outside the vehicle. This easy to bolt-on emissions-legal system features large dual 3.00 in. mandrel-bent stainless steel tubing with our exclusive Scavenger Series® X-pipe flowing into a pair of our race-proven Outlaw Series mufflers for a deep aggressive sound and maximum power. The exhaust system uses the factory hanger locations for an easy installation and the mufflers include our high quality exhaust valves and actuator stands to retain your factory actuator motors that control the active exhaust. The system finishes off with quad 4.00 in. black ceramic coated 304 stainless steel tips giving your Pony the look and sound it deserves. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage. The system includes all necessary parts, hardware and easy to follow instructions. Covered by our Lifetime Limited Warranty. Notes: Fits Coupes and Convertibles with Factory Active Exhaust.
