Mustang Owners Rejoice: Mustang GT 2018 Systems are Here.
Stainless Works performance systems now available for the new 2018 Mustang GT. Gain roaring sound and increase flow with these sick catbacks and powerful headers.
New for the 2018+ Mustang GT: Stainless Works' Redline and Legend series exhausts.
The Redline Series
Our Redline series is designed to get the most aggressive sound out of your ride. We design Redline systems to maximize the volume and tone of the engine, while still eliminating any drone in the cabin. Resulting in a feeling that will make you want to high-five your friends in the face.
The Legend Series
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, improved tone with restrained loudness. A system that still gets the blood flowing, but allows for a comfortable ride.
Performance and Sound Proudly Made in the USA
We take our years of experience, and inject that knowledge into creating performance systems that maximize horsepower, torque and sound. Each system is designed for the specific vehicle with distinct features to get the most performance possible along with great fitment.
Made to withstand grueling engine conditions, Stainless Works exhaust and headers are fabricated from 304 stainless steel, which not only resist corrosion, but is more durable than its aluminized steel or 409 stainless steel counterparts.
Features: ‣ 304 stainless steel construction ‣ TIG welded for strength ‣ Mandrel bent (no buckling) for optimal flow ‣ Legend or Redline Series Sound Options ‣ Designed and Made in Streetsboro, Ohio, USA

Make It Your Own With Custom Options
Choose Your Connection
Stainless Works Mustang GT 2018 systems come in Factory Connect configuration.
Factory Connect allows our headers or exhaust to connect to the factory exhaust or manifolds respectively. They connect to the factory location on either end or can connect to each other for a full Stainless Works system.
Performance Connect is designed to take advantage of performance gains not possible with the standard factory connection point. Both SW headers and SW exhaust are used in this configuration. In the case of the G8, we’ve developed a system which uses an X-pipe to create a true-dual system which doesn’t neck-down.
Aftermarket Connections Another option to make your ride uniquely yours, Stainless Works is offering a new configuration for Mustang Headers: Aftermarket Connections. With this version of headers with extended leads, you can connect to a handful of catbacks for your ride. SW Factory Connect, MBRP, and Corsa catbacks can all link up with this new "Unholy Union" option, available now!
Valve or No Valve
That's the question. Whether it is honorable to have Active Exhaust valves on your system or not, we're not here to make that judgement call. But we made exhaust systems for both. Now whether your ride is equipped with these little guys or not, you'll be supported by Stainless Works for your build. So go ahead and configure your upgrades to fit your ride- just like a glove.
Improve sound and performance on your 2018+ Mustang GT with this Redline catback from Stainless Works. We’ve engineered a drone free aggressive muffler tuned specifically for this improved coyote engine from Ford. Featuring the latest in active exhaust technology, our in-house engineered valve bolts directly to the factory electronics to allow for all exhaust modes. From the closed valve “Quiet” mode, to the chambered “Normal” mode and to the wide open straight through design on the “Track” mode.
In addition to the tuned mufflers, we’ve also utilized 3” tubing into our h-pipe crossover for an improvement in flow over the stock exhaust. Finishing the system off we utilized polished quad tips with a double wall conical style. This system is built from corrosion resistant 304 stainless steel and TIG welded at our state of the art facility in Streetsboro, Ohio. As always we stand by our products with a lifetime warranty on material and craftsmanship.
This system is designed for vehicles with the Active Valve Performance Exhaust. Not confirmed to fit convertibles.
