Header Flanges

CNC laser cut header flanges and exhaust flanges, made in the USA from high-quality stainless steel. Precision cutting ensures a consistent port match and flat sealing surface every time, so you spend less time fitting and more time welding.

Designed for custom header fabrication, engine swaps, and performance exhaust builds, our flanges are compatible with a range of applications including LS swaps and other popular platforms. Each flange features clean laser-cut edges that are weld-ready right out of the box.
