Description

Enhance the power, efficiency, and sound of your 2004–2008 Ford F-150 5.4L Triton V8 with the Stainless Works Long Tube Headers featuring 1-3/4” primary tubes, 2-1/2” lead pipes, high-flow catalytic converters, and a factory-connect Y-pipe. Precision-crafted in the USA using 304 stainless steel, this header system is designed for performance-minded drivers looking for a direct-fit, emissions-conscious upgrade that retains compatibility with the factory exhaust system.

The headers start with 3/8" thick laser-cut flanges for superior sealing and long-term durability. From there, mandrel-bent 1-3/4" primaries guide exhaust gases smoothly to the slip-fit 2.5” collectors equipped with integrated merge spikes—a performance feature that optimizes scavenging and reduces turbulence. The system continues through high-flow catalytic converters, improving flow while keeping emissions compliance in mind, and finishes with a Y-pipe that aligns with the factory connection point.

Perfect for daily driving or towing, this system delivers a noticeable bump in throttle response, horsepower, and torque, while providing a rich, authoritative exhaust tone. Designed specifically for SuperCrew models with 5.5' or 6.5' beds and SuperCab models with 6.5' beds, this kit ensures proper fitment and performance for your F-150 application.
