2018+ Mustang GT 5.0L Redline 3" Catback Exhaust with X-Pipe & Active Valve – Stainless Works

Transform the sound and performance of your 2018+ Ford Mustang GT 5.0L with the Stainless Works Redline 3" Catback Exhaust System featuring an X-Pipe and Active Valve technology. Engineered for enthusiasts who demand aggressive tone and track-ready performance, this exhaust system amplifies the iconic roar of the Coyote V8 while maintaining drone-free comfort inside the cabin.

The Redline Series delivers Stainless Works’ most aggressive exhaust note. Dual-mode mufflers with a 3" active valve assembly let you choose between Track Mode (straight-through, maximum volume and power) and Quiet Mode (chambered, refined sound). Designed in-house, the electronic valve integrates seamlessly with your Mustang GT’s factory Active Valve Performance Exhaust system, allowing you to retain full control of all exhaust modes.

Built from premium 304 stainless steel for superior strength and corrosion resistance, each tube is CNC mandrel-bent for smooth airflow and horsepower gains. TIG-welded construction ensures long-lasting durability. The system exits through bold quad 4" slash-cut, double-wall polished conical tips, giving your Mustang an aggressive stance to match its sound. All hangers and clamps are included for a straightforward installation, and the system mates directly to Stainless Works headers via the performance connection point.
