Premium Shorty Headers. The JBA 1-5/8-Inch Shorty Headers; Natural are designed to replace restrictive stock manifolds, helping to increase engine power and efficiency. They provide a direct replacement exhaust pathway that promotes smoother exhaust flow for trucks and SUVs equipped with V8 engines.

Construction and Appearance. Manufactured from durable stainless steel tubing that is mandrel bent for smooth airflow, these headers feature a proprietary Firecone collector for effective exhaust scavenging.
