The JBA Cat4Ward shorty header for 2004–2008 Ford F-150 4.6L 2V uses 1-1/2" primaries in raw 409 stainless. JBA shorty headers are less restrictive than stock manifolds, helping improve exhaust flow and engine efficiency. The Firecone collector applies race-proven flow tuning, while mandrel-bent tubing, 3/8" machined flanges, oversized ports and extra-thick collector domes combine with factory-style emission connections for dependable installation.
