Stainless Works 18+ Ford Mustang GT Redline Cat-Back Performance Connect H-Pipe w/ Active Valves

The 3-inch, 304 stainless steel tubing in this Stainless Works Redline cat-back exhaust is CNC mandrel bent. This design choice is crucial because it maintains the tube's diameter through bends, which helps the exhaust gases flow more freely. For your 2018-2020 Mustang GT with the 5.0L V8 and active valve performance exhaust, this means a noticeable improvement in both sound and performance.

Stainless Works engineered this Redline series system to give your Mustang GT a more aggressive sound, specifically tuning the mufflers to maximize the volume and tone of the 5.0L engine without introducing cabin drone. It incorporates a 3-inch valve assembly that connects directly to your car's factory electronics, allowing you to switch between exhaust modes. You get a straight-through 'Track' mode for maximum volume and a chambered 'Quiet' mode for a more subdued tone. The system exits through four polished, slash-cut, double-wall conical tips, giving your Mustang a distinct look.

This cat-back system is designed to bolt up to the performance connection point, especially if you're already running Stainless Works headers. It includes all the necessary hangers and clamps for installation. While it's designed for vehicles with active valve performance exhaust, it has not been confirmed to fit convertible models. The entire system is TIG welded for strength and durability, finished in a mill finish, and backed by a lifetime warranty, proudly made in the USA.
