JBA 99-04 Ford Mustang 4.6L 2V 1-5/8in Primary Silver Ctd Cat4Ward Header

JBA is known for making well-built exhaust components that help your vehicle perform better. If you're looking to get more out of your 1999-2004 Ford Mustang's 4.6L 2-valve engine, these JBA Cat4Ward® shorty headers are a solid option. They replace the restrictive factory exhaust manifolds with a design that allows your engine to breathe more freely, which can lead to improved power and efficiency.

These headers are constructed from durable stainless steel tubing, chosen for its ability to handle the heat and stress of daily driving, towing, or even racing. The 3/8-inch thick flanges are machined for a flat mating surface, and the oversized exhaust ports are designed to match the engine's cylinder heads. A key feature is JBA's proprietary Firecone collector, which uses race-proven technology to help maximize power and torque gains in the RPM range you'll use most often. The tubing is mandrel-bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. They also include factory-style emission connections, so you can retain your emissions equipment, and come with high-quality hardware for a professional, no-leak installation.

When installing these headers, you'll want to refer to the manufacturer's instructions for the best results, especially regarding the included hardware. Because these are designed as a direct replacement for your stock manifolds, they should fit right onto your 1999-2004 Mustang without major modifications.
