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 stronger than its aluminum or steel counterparts.

Increased Power: Factory manifolds can be restrictive and hold back the true potential of your ride. Stainless Works' systems unlock the power of your engine. Our long tube, free-flowing design reduces back pressure, 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.
