This Flowmaster Outlaw Axle-back exhaust system is specifically designed for 2015-17 Ford MustangGT coupes and convertibles with the 5.0L engine. The system features all stainless steel mandrel bent tubing leading into a pair of our race-proven Outlaw series mufflers, for an aggressive exterior sound level with a noticeable interior sound level. The system finishes with a pair of large 4.00-inch black ceramic coated tips for an aggressive look that matches the attitude of the Outlaw sound level.
