The JBA Cat4Ward shorty header for 1997–2003 Ford F-150 5.4L 2V uses 1-1/2" primaries in raw 409 stainless. JBA shorty headers are much less restrictive than stock manifolds, helping improve engine efficiency and throttle response. The Firecone collector applies race-proven tuning, while mandrel-bent tubes, 3/8" machined flanges, oversized ports and extra-thick collector domes combine with factory-style emission connections for a trusted fit.
