Return PolicyJBA 6616SJS long-tube headers are designed to unlock stronger horsepower and torque across the RPM range in 1965–1973 Mustangs. The full-length layout uses large 1.75" mandrel-bent primary tubes and oversized exhaust ports to improve cylinder evacuation, helping the engine breathe better at higher RPM where stock manifolds tend to choke flow.
These headers use thick 3/8" one-piece flanges for a stable, leak-resistant seal and JBA’s Firecone® merged collector design to smooth the transition into the collector for better scavenging. They’re finished in a semi-gloss grey metallic ceramic coating for heat control and durability, and the kit includes gaskets and mounting hardware for a clean, professional install. (Listed for closed-course competition use.)
