Stainless Steel Headers Manifolds For Ford F250 F350 F450 (1997-2003) with 7.3L Powerstroke Diesel Engine

Stainless Steel Performance Headers for Ford 7.3L Powerstroke (1997–2003)

Unleash the full potential of your 7.3L Powerstroke Diesel with these Stainless Steel Performance Headers, engineered specifically for 1997–2003 Ford F-250, F-350, and F-450 trucks. Designed as a direct replacement for restrictive factory exhaust manifolds, these headers deliver measurable performance gains, improved exhaust flow, and a deeper, more aggressive diesel sound—without sacrificing durability or reliability.

The legendary 7.3L Powerstroke is known for its longevity, towing strength, and workhorse reputation. These stainless steel headers build on that heritage by reducing exhaust backpressure and improving scavenging efficiency, allowing your engine to run cooler, breathe better, and perform more efficiently under load.

Real Performance Improvements Where It Matters

Upgrading to tubular stainless headers helps lower exhaust gas temperatures (EGTs) while improving throttle response, torque, and horsepower. Many owners also experience improved fuel economy, especially during towing or highway driving, thanks to more efficient exhaust flow and reduced engine strain.

Whether you use your truck for towing, hauling, or daily driving, these headers help your 7.3L Powerstroke deliver smoother power and stronger pull throughout the RPM range.

Built to Last in Harsh Diesel Conditions

Constructed from high-quality stainless steel, these headers are performance-tested and built to withstand extreme heat cycles, corrosion, and long-term use. Unlike factory cast manifolds that can crack or warp over time, stainless tubular headers offer superior durability and consistent performance.

In addition to performance gains, these headers produce an incredibly unique and aggressive exhaust tone, enhancing the driving experience without sounding harsh or uncontrolled.

Direct Bolt-On Installation

These headers are intended as a direct replacement for the stock exhaust manifolds and install using factory mounting locations. The kit includes two gaskets for a complete installation and all required header mounting hardware.

No cutting or welding is required, and the upgrade will not void your vehicle’s warranty, making it a safe and effective performance enhancement.
