The JBA Cat4Ward shorty header for 2011–2014 Ford F-150 5.0L Coyote uses 1-5/8" primaries in raw 409 stainless. These headers are less restrictive than factory manifolds and help improve exhaust flow and engine efficiency. A Firecone collector tuned for torque, mandrel-bent stainless tubing, 3/8" machined flanges, oversized ports and extra-thick collector domes combine with factory-style emission connections for a secure, professional installation.
