The JBA Cat4Ward shorty header for 2014–2019 GM trucks with 5.3L or 6.2L DFI engines uses 1-5/8" primaries and a silver-coated finish to resist corrosion while improving flow. Built from stainless components, it combines 3/8" machined flanges, mandrel-bent tubing and JBA's Firecone collector to boost power and torque in everyday driving. Factory-style emission connections and included hardware support a clean, no-leak installation.
