JBA 99-04 Ford Mustang 4.6L 4V 1-5/8in Primary Ti Ctd Cat4Ward Header

When you're looking to get more out of your 1999-2004 Ford Mustang with the 4.6L 4-valve engine, this JBA Cat4Ward header set is what you get. Inside the box, you'll find the headers themselves, constructed from mandrel-bent stainless steel tubing, along with factory-style emission connections and all the necessary high-quality hardware for installation. These headers are designed to replace your restrictive stock exhaust manifolds, which can really choke up an engine, especially one like the 4.6L 4V.

JBA builds these headers with 3/8-inch thick machined flanges that have oversized exhaust ports, helping to ensure a solid seal and better flow right from the cylinder head. The real trick here is JBA's proprietary Firecone collector design. It's a race-proven technology that's specifically tuned to create maximum power and torque gains in the RPM range where you'll be doing most of your driving, whether that's cruising around town or hitting the track. The stainless steel construction means they're built to handle the heat and stress of daily driving, towing, or even racing without issue.

Installing these headers is a direct replacement for your factory manifolds, and they come with the hardware needed for a professional, no-leak setup. You'll notice an improved exhaust note and a more responsive engine once they're on.
