The JBA Cat4Ward shorty header for 1997–2003 Ford F-150 4.6L 2V uses 1-1/2" primaries in raw 409 stainless. JBA shorty headers reduce restriction versus stock manifolds to enhance engine efficiency and responsiveness. The Firecone collector applies race-proven flow tuning, while mandrel-bent tubing, oversized exhaust ports, 3/8" machined flanges and extra-thick collector domes provide durable construction and factory-style emission connections for a secure fit.
