JBA 97-03 Ford F-150 5.4L 2V 1-1/2in Primary Silver Ctd Cat4Ward Header

JBA is known for making performance exhaust parts that help your vehicle breathe easier and make more power. These Cat4Ward headers are a prime example, designed to replace the restrictive stock exhaust manifolds on your 1997-2003 Ford Expedition, F-150, or Lincoln Navigator with the 5.4L 2V engine. By letting your engine exhale more freely, you can expect improved power and efficiency across the board, especially in the RPM range where you do most of your driving.

These headers are built from strong stainless steel tubing, which means they're made to handle the demands of daily driving, towing, or even racing without issue. The 3/8-inch thick machined flanges are extra thick and have oversized ports to match the exhaust ports on your engine, ensuring a solid seal and good flow. JBA's proprietary Firecone collector design is a key feature, using proven race technology to maximize power and torque gains. They also include factory-style emission connections and high-quality hardware, which helps ensure a professional installation without leaks.

When installing these headers, you'll want to make sure you have the right tools and potentially a helper, as exhaust work can sometimes be tricky. It's always a good idea to refer to the manufacturer's installation instructions for the most accurate guidance. These headers are a significant upgrade for your truck or SUV's exhaust system.
