The JBA Cat4Ward header for 1996–2000 GM trucks with 5.0L or 5.7L SBC engines without A.I.R. is a compact shorty header that reduces exhaust backpressure to boost driveability. Ti-coated over mandrel-bent 1-1/2" primaries, it employs JBA's Firecone collector, 3/8" thick machined flanges with oversized ports, extra-thick collector domes and factory-style emission connections with hardware for a secure, leak-free installation.
