JBA 07-14 Ford GT500 5.4/5.8L 4V 1-5/8in Primary Silver Ctd Cat4Ward Header

Starting with the 3/8" thick machined flanges and oversized exhaust ports, these JBA Cat4Ward headers are built to handle the demands of your 2007-2014 Ford Mustang GT500 with the 5.4L or 5.8L 4V engine. They are significantly less restrictive than the factory exhaust manifolds, which can lead to noticeable gains in engine power and efficiency. The primary tubing measures 1-5/8 inches, designed to work well with your engine's displacement and exhaust flow characteristics.

Constructed from durable stainless steel, these headers are made to endure daily driving, towing, or even racing conditions. JBA's proprietary Firecone collector design is a key feature, utilizing race-proven technology to help maximize power and torque gains in the RPM range where you'll be driving most often. The tubing is mandrel bent to maintain consistent diameter throughout, ensuring smooth exhaust flow. You'll also find extra thick collector domes for added durability.

Installation is made more straightforward with the inclusion of factory-style emission connections, allowing you to retain your vehicle's emissions equipment. High-quality hardware is also included to help ensure a professional, no-leak installation. These headers are a solid option if you're looking to improve your Mustang's performance and exhaust note.
