JBA 97-03 Ford F-150 4.6L 2V 1-1/2in Primary Silver Ctd Cat4Ward Header

If you're looking to get more out of your 1997-2003 Ford Expedition with the 4.6L 2V engine, these JBA Cat4Ward® shorty headers are a solid option. They replace the factory exhaust manifolds, which are known to be quite restrictive, and are designed to help your engine breathe easier. This means you can expect an improvement in both power and overall efficiency, making your truck feel more responsive, especially in the lower and mid-range RPMs where you do most of your driving.

JBA builds these headers from durable stainless steel tubing, which holds up well over time and resists corrosion. The 3/8-inch thick flanges are machined for a flat, leak-free seal against the cylinder heads, and they feature oversized exhaust ports to match the engine's flow needs. A notable feature is JBA's proprietary Firecone collector design, which uses proven race technology to help maximize torque gains. They also include factory-style emission connections, so you can retain your emissions equipment for a cleaner exhaust system, and come with high-quality hardware to ensure a professional installation.

When installing these headers, you'll want to make sure you have the right tools and potentially a helper, as working on exhaust components can sometimes be tricky. It's also a good idea to have new exhaust gaskets on hand for the connection to your existing exhaust system. These headers are designed to be a direct fit for the specified Ford Expedition and F-150 models, simplifying the installation process.
