The JBA Cat4Ward header for 2002–2013 GM trucks covering 4.8L and 5.3L LS engines without EGR is offered with a silver-coated finish over mandrel-bent 1-1/2" primaries to resist corrosion while improving flow. It uses JBA's Firecone collector, 3/8" machined flanges and oversized ports, extra-thick collector domes and includes factory-style emission connections and quality hardware for a professional fit.
