About the manufacturer

Introducing the Flowmaster Outlaw® Cat-back exhaust system for the 2013-2014 Ford Mustang GT with 5.0L engine. This system is perfect for the person looking for a deep powerful exterior sound while maintaining a moderate interior sound level with all of the performance benefits that you would expect from Flowmaster®. New features include dual 3.00-inch mandrel-bent stainless steel tubing flowing into a Scavenger Series® X-pipe for maximum performance and a deep unique muscle tone. The Scavenger Series X-pipe then flows into a pair of race-proven Outlaw® mufflers and out into the dual 3.00-inch mandrel-bent tailpipes. The tailpipes use the factory hanger locations and are finished off with large 4.00-inch polished stainless steel tips to complement the factory cutouts. Designed for an easy installation this system includes all necessary parts, hardware, and detailed instructions. Note: Fits Coupes and Convertibles.
