The JBA Cat4Ward shorty header for 2005–2010 Ford F-250 and F-350 with the 5.4L 3V engine uses 1-5/8" primaries in raw 409 stainless. JBA shorty headers are significantly less restrictive than stock manifolds and boost engine efficiency. The Firecone collector and mandrel-bent tubes maximize flow, while 3/8" machined flanges, oversized ports, factory-style emission connections and heavy collector domes ensure a professional fit.
