Description
Unleash the iconic muscle sound of your 2020 Ford Mustang GT500 with the Stainless Works Legend Series Catback Exhaust System, featuring a traditional H-pipe crossover and polished quad 5" slash-cut tips. Designed to enhance both performance and sound, this premium exhaust system offers improved flow, factory active valve integration, and a deep, aggressive tone that stays true to the heritage of American muscle.
This system is part of Stainless Works’ Legend Series—tuned for a classic muscle car rumble with zero drone inside the cabin. The 3" mandrel-bent tubing is engineered for optimal exhaust velocity and reduced backpressure, feeding into a performance H-pipe that balances the left and right banks of the engine for enhanced low-end torque and refined acoustics.
The system includes active exhaust valves that seamlessly integrate with the GT500’s factory drive modes. Whether cruising quietly in “Quiet” mode, enjoying a refined chambered sound in “Normal,” or opening it wide up in “Track” mode, you retain full control of your exhaust note. The active valve system bolts directly to the OEM electronic valve system, ensuring flawless compatibility.
Handcrafted from corrosion-resistant 304 stainless steel and TIG welded for superior strength and finish, this catback exits through the factory valance with a bold set of polished quad 5" double-wall slash-cut tips, delivering a track-ready look that matches the GT500’s aggressive rear fascia.
