Product Description

The JBA 6610S Long Tube Headers are performance exhaust headers engineered specifically for 1965-1973 Ford Mustang models equipped with small block V8 engines (260/289/302). These long tube headers replace restrictive stock manifolds with mandrel-bent 1.75" stainless steel tubes and Firecone® merged collectors to improve exhaust scavenging, boost horsepower, and increase torque throughout the RPM range.

Constructed with thick CNC-machined flanges, oversized ports, and a design that maximizes ground clearance, the 6610S headers include all necessary hardware and gaskets for installation. While not emissions legal in all regions, they are ideal for performance builds, restoration projects, or race applications where maximum flow and power gains are desired.
