JBA Cat4Ward headers for 2007–2014 Ford GT500 5.4/5.8L 4V come with 1-5/8" primaries and a silver coating. Built as shorty-style headers, they are less restrictive than stock manifolds and use JBA’s Firecone collector to deliver improved torque and efficiency in real-world driving. The package includes factory-style emission connections and hardware, plus 3/8" machined flanges, oversized exhaust ports, mandrel-bent tubing and extra-thick collector domes for durability.
