Fits 2015-2017 Ford Mustang models including GT, EcoBoost, V6, and Shelby GT350/GT350R (5.0L).

Give your S550 Mustang a more aggressive acoustic profile and improved exhaust flow with the Roush Axle-Back Exhaust Kit. This system replaces the restrictive factory mufflers with high-flow units designed to produce a deep, throaty V8 growl at idle that builds into a powerful roar under heavy acceleration. Each system is engineered to reduce backpressure, helping your engine breathe more efficiently.

Built for durability and longevity, this kit is constructed from T-304 stainless steel to resist corrosion and environmental wear. The mandrel-bent tubing ensures a constant internal diameter throughout every bend, eliminating kinks and turbulence for maximum flow velocity. The kit features polished round tips that provide a finished, performance-oriented look to the rear of your vehicle.
