Overview

Upgrade your 2018–2023 Mustang GT with this powerful axleback system from Stainless Works.

Made to unleash your 5.0L engine with the powerful roar it deserves, this axleback is designed for a Factory Connection behind the rear suspension of the vehicle and smooth installation.

Featuring a quad-tip exhaust with beautiful and robust 4" slash-cut conical double-wall tips, this system lets you choose the finish that best matches your Mustang GT.

Our Legend series is designed to create our signature growl, increase volume over stock, yet maintain a comfortable cabin environment.

We design Legend systems with the daily-driver in mind, giving you improved tone with restrained loudness — a system that still gets the blood flowing, but allows for a comfortable ride.

Our Redline series is designed to get the most aggressive sound out of your ride, maximizing the volume and tone of the engine while still eliminating drone in the cabin.

This system is designed for standard non-valve vehicles. Not confirmed to fit convertibles.

Built from corrosion-resistant 304 stainless steel and TIG welded at our state-of-the-art facility in Streetsboro, Ohio, this axleback is backed by a lifetime warranty on materials and craftsmanship.
