Product Description

The Roush 422097 Axle-Back Exhaust is engineered specifically for 2018-2025 Ford Mustang GT models equipped with the 5.0L V8 engine to enhance both performance and sound character. This premium exhaust system replaces the factory rear section with mandrel-bent stainless steel tubing and high-flow mufflers, improving exhaust flow and reducing back pressure for a more aggressive and performance-oriented sound. The polished quad 304 stainless steel tips add a bold visual upgrade at the rear, while durable construction ensures long-term corrosion resistance for daily driving or spirited use.

Installation is straightforward, using factory mounting points and hangers - no cutting or welding is necessary on most applications. The system produces a richer, race-inspired exhaust tone without excessive drone inside the cabin, making it a balanced choice for drivers seeking a performance upgrade that enhances both auditory presence and engine breathing. Fitment includes most Mustang GTs from 2018 up to 2025, though active exhaust versions on some trims may require additional considerations.
