Stainless Steel Headers Manifolds for Ford F250 F350 F450 (1999-2003) 7.3L Powerstroke Diesel Engine

Let Your 7.3L Powerstroke Finally Breathe

The Ford 7.3L Powerstroke (1999–2003) is arguably the most respected diesel engine ever put in a consumer truck. Known for its "million-mile" durability and massive towing capability, it is a true workhorse. However, the factory cast-iron exhaust manifolds are a notorious bottleneck. They restrict exhaust flow, retain massive amounts of heat, and are prone to cracking over time, which robs your engine of power and efficiency.

Protect your investment and unlock hidden power with our Stainless Steel Performance Headers. Engineered specifically for the 1999–2003 F-Series platform, these tubular headers replace the restrictive stock logs to smooth out exhaust pulses. The result is a more efficient engine that runs cooler, pulls harder, and sounds like the beast it was meant to be.

Why Swap to Tubular Headers?

If you tow heavy loads or drive highway miles, managing Exhaust Gas Temperatures (EGTs) is critical. These headers are designed to get heat out of the engine bay efficiently.

• Lower EGTs: By reducing backpressure and improving scavenging, these headers lower exhaust gas temperatures, giving you a wider safety margin when towing up steep grades.
• Durability Over Stock: Unlike factory cast manifolds that can warp and crack under thermal stress, our high-quality stainless steel construction is built to withstand extreme heat cycles and corrosion.
• Throttle Response & Torque: With improved flow, your turbo spools faster. Expect a sharper throttle response and smoother power delivery throughout the RPM range.
• Aggressive Diesel Tone: Ditch the muted factory sound. These headers produce a deeper, unique, and aggressive exhaust note that enhances the driving experience without being overbearing.
• Efficiency Gains: A breathing engine is an efficient engine. Many owners report improvements in fuel economy (MPG) during cruising and towing due to reduced engine strain.
