JBA 99-04 Ford Mustang 4.6L 2V 1-5/8in Primary Raw 409SS Cat4Ward Header

If you're looking to get more out of your 1999-2004 Ford Mustang's 4.6L 2V engine, these JBA Cat4Ward headers are a solid choice. They replace the stock exhaust manifolds, which can be quite restrictive, allowing your engine to breathe much better. This improved airflow translates directly into more power and better efficiency, making your Mustang feel more responsive, especially in the RPM range where you do most of your driving.

These headers are built from durable 409 stainless steel tubing, which holds up well to the demands of daily driving and even harder use. The flanges are a stout 3/8-inch thick with oversized exhaust ports to ensure a good seal and smooth flow into the primary tubes. JBA uses their proprietary Firecone collector design, which is a race-proven technology aimed at maximizing power and torque gains. They also include factory-style emission connections, so you can maintain your emissions equipment, and come with high-quality hardware for a professional installation that's less likely to leak.

You'll find that the mandrel-bent tubing helps maintain consistent diameter throughout the bend, further aiding exhaust flow. The extra thick collector domes add to the overall robustness of the header. This is a well-built component designed to give your Mustang a noticeable performance boost.
