The JBA mid-length header for 1965–1973 Mustang 351W with T-5 and cable clutch uses 1-5/8" primaries and a raw 409 stainless finish to withstand daily driving and racing. Its shorty form reduces restriction to improve power and efficiency while the Firecone collector, mandrel-bent tubing, machined 3/8" flanges and extra-thick collector domes deliver durable, focused torque gains and include factory-style emissions connections and installation hardware.
