The JBA Cat4Ward header for 1992–1995 Chevrolet Blazer and compatible GM trucks with 5.0L/5.7L SBC engines (without A.I.R.) is a shorty upgrade to reduce restriction and improve engine efficiency. It uses mandrel-bent stainless tubing, 3/8" machined flanges with oversized ports and the Firecone collector, and includes factory-style emission connections and durable hardware for a leak-free installation.
