    Stainless Works Headers

    Posted by Ryan Miller on May 9th 2026

    I purchased a set over a year and half ago for my 2018 GT350. These headers have held up great with zero issues! I just recently took them off the car to wrap them and I have to say I’m impressed with the quality and craftsmanship that went into them even after a year of getting beat on. I will definitely be buying another set for my 2025 F-150 here soon in the near future! Great job SW!! ❤️
