Product Details

Built from T-304 stainless steel, this Roush axle-back exhaust system is designed to resist corrosion and staining, ensuring it holds up well over time. If you're looking to give your 2015-2023 Ford Mustang, whether it's the 3.7L V6 or the 2.3L EcoBoost, a more aggressive sound and a sharper appearance, this kit is a solid choice. Ford's stock exhaust often leaves Mustang owners wanting a deeper, more powerful tone, and Roush aims to fill that gap.

This system features single-tip high-flow chambered mufflers that contribute to both an improved sound and better performance. The mandrel bends used in its construction help maintain consistent high flow and reduce backpressure throughout the exhaust path. Because it uses the factory mounting points, installation is straightforward on both V6 and I4 models without needing any modifications or welding, making it a practical upgrade for your Mustang.
