Performance and Sound Proudly Made in the USA

Innovative Design

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.

Solid Construction

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.


‣ 304 stainless steel construction
‣ TIG welded for strength
‣ Mandrel bent (no buckling) for optimal flow
‣ Designed and Made in Chagrin Falls, Ohio, USA

Make It Your Own With Custom Options

Stainless Works designs our systems with modular components, which allow you the freedom to decide the perfect horsepower system for your ride.

Choose Your Connection

Stainless Works Ford Focus RS System comes in Factory Connect configuration. You can buy either system for Factory connection on your vehicle, or buy both and gain a full 3-inch system of roaring power stainless steel. That's how we'd have it at Stainless Works.

Factory Connect

Allows our headers or exhaust to easily bolt to the factory exhaust or manifolds respectively. They connect to the factory location which is necked-down to accommodate fitment. But this Factory Connection is particularly special: it still fits our Stainless Works systems.

Valve Included

No detail overlooked. Our Ford Focus RS Catback system from Stainless Works includes a welded, integrated housing for the valve on the new-generation catbacks. We're here to upgrade you, never give you less.

Increased Power

Factory downpipes can be restrictive and hold back the true potential of your ride. Stainless Works' systems unlock the power of your engine. Our free-flowing design reduces resistance, and will bring new found power that you can feel and hear.

Limited Lifetime Warranty

Stainless Works headers and exhausts are designed to take the punishment of your motor, and are backed by a Limited Lifetime Guarantee on material and workmanship.

Install-Ready

We want to make sure installation goes as smoothly as possible, that's why Stainless Works systems come Install-Ready. Whether clamps, O2 extensions, bolts or RTV silicone, our headers and exhausts come with all necessary accessories to make installation as smooth as possible.
