Maximize your Mustang’s performance with Stainless Works Long Tube Headers, designed specifically for the 2015–2025 Ford Mustang GT 5.0L. Whether you're building a high-horsepower street car or a dedicated track machine, these headers offer the perfect blend of performance, sound, and premium craftsmanship.

Made in the USA using high-grade 304 stainless steel, these headers are designed for superior strength, corrosion resistance, and long-term durability. The 1-7/8" primary tubes and 3” merge collectors deliver maximum flow and power gains throughout the RPM range — making them ideal for both naturally aspirated and forced induction setups.
