Construction & Design

The JBA Shorty Header is crafted from premium stainless steel tubing that is mandrel bent to maintain consistent diameter and smooth bends, reducing exhaust restrictions. The titanium ceramic coating not only provides a sleek appearance but also offers excellent thermal insulation, helping to keep engine bay temperatures lower and protecting surrounding components. The thick machined flanges ensure a perfect fit against the cylinder head, minimizing leaks and improving exhaust scavenging efficiency.

JBA’s proprietary Firecone collector technology is a standout design element that enhances exhaust gas velocity and scavenging, translating into improved horsepower and torque where it matters most during everyday driving and off-road conditions.
