The JBA Cat4Ward shorty header for 2014–2019 GM trucks with 5.3L or 6.2L DFI engines uses 1-5/8" primaries and raw 409 stainless construction to open exhaust flow and improve efficiency. It pairs 3/8" machined flanges and mandrel-bent tubes with JBA's Firecone collector to extract torque where you drive most. Factory-style emission connections, oversized ports and heavy-duty hardware make for a durable, professional fitment.
