The JBA Cat4Ward shorty header for 2005–2010 Ford F-Series 5.4L 3V uses 1-5/8" primaries with a titanium-coated finish. JBA shorty headers reduce manifold restriction to improve engine efficiency and response. The Firecone collector design and mandrel-bent tubing optimize exhaust flow, while 3/8" machined flanges, oversized ports, extra-thick collector domes and factory-style emission connections support a reliable, no-leak installation.
