Introducing our new American Thunder® Axle-back exhaust system featuring our new W.A.V.E. Technology™ (Wireless Active Valve Exhaust™) for all 2018-2019 Ford Mustang GT 5.0L coupes and convertibles, originally equipped WITHOUT the Factory Active Performance Exhaust Option. This trick new stainless steel exhaust system has two wireless remotes that control the high-quality actuators and exhaust valves included with the specially designed mufflers incorporating Outlaw® muffler technology.

The system is finished off with quad 4.00-inch polished 304 stainless steel tips for an aggressive look that demands attention. Includes all necessary parts, hardware and detailed instructions for an easy installation you can do at home. Covered by the Flowmaster® Lifetime Limited Warranty. Want even more sound?
