JBA 05-10 Ford Mustang 4.6L 3V 1-5/8in Primary Raw 409SS Cat4Ward Header

JBA is known for making exhaust components that help your vehicle breathe better, and these Cat4Ward® shorty headers are a prime example for your 2005-2010 Ford Mustang with the 4.6L 3V engine. Stock exhaust manifolds can really choke up an engine, limiting its ability to make power and use fuel efficiently. These JBA headers are designed to be much less restrictive, helping your engine perform at its best. They are built from durable 409 stainless steel, which means they're made to handle the demands of daily driving, towing, or even track use.

What sets these headers apart is JBA's proprietary Firecone collector design. This isn't just about looks; it's a race-proven technology aimed at maximizing power and torque gains right where you need them most – in the typical RPM range you use every day. The primary tubes are 1-5/8 inches in diameter, and the flanges are a solid 3/8 inch thick with oversized exhaust ports to ensure a good seal and smooth flow. They also include factory-style emission connections, making it easier to hook up your emissions equipment for a cleaner, more compliant exhaust system. You'll also find extra thick collector domes for added durability.

When you're ready to install these, JBA includes high-quality hardware to help ensure a professional, no-leak installation. This is a significant upgrade over stock manifolds, and you should notice an improved throttle response and a more aggressive exhaust note.
