This Flowmaster Outlaw Axle-back exhaust system is specifically designed for all 2015-17 Ford Mustang GT with the 5.0L engine and fits both coupes and convertibles. The system features a pair of race-proven Outlaw mufflers for a very aggressive exterior sound, with a moderate interior sound level. The axle-back system starts off with 2.50-inch connections for an easy fit to the factory stock mid-pipe, then quickly transitions to the large 3.00-inch mandrel-bent tubing for free flow into the Outlaw mufflers. The system is supported from the factory hanger locations and is finished off with a pair of large 4.00-inch polished stainless steel tips for that performance look and sound your Pony deserves.
