JBA 97-03 Ford F-150 4.6L 2V 1-1/2in Primary Raw 409SS Cat4Ward Header

This is the JBA Cat4Ward header system for your 1997-2003 Ford Expedition with the 4.6L 2V engine. These headers replace your restrictive factory exhaust manifolds, helping your engine breathe better and make more power. If you're looking to get a bit more pep out of your Expedition, especially for towing or just daily driving, this is a solid upgrade.

JBA builds these headers from tough 409 stainless steel tubing, so they're made to last. The primary tubes are 1-1/2 inches, and they feature a 3/8-inch thick flange with oversized exhaust ports for a good seal and improved flow. A notable feature is JBA's proprietary Firecone collector design, which is developed using race-proven technology to maximize power and torque gains in the RPM range you'll use most often. They also include factory-style emission connections and all the necessary hardware for a professional installation that won't leak.

When installing these, you'll want to make sure you have the right tools for exhaust work, and it's always a good idea to refer to the manufacturer's instructions for the best results. This header set is designed to be a direct fit, making the installation process as straightforward as possible.
