Exhaust manifold flanges

Exhaust manifold flanges are used when building or adapting an exhaust manifold where a correct and stable connection is needed between the cylinder head, manifold or the rest of the turbo setup. They are often used in custom-built projects, motorsport and performance builds where fitment, port shape and material choice have a major impact on the finished result. A correct flange helps provide a better starting point for both installation and further welding work.

When choosing an exhaust manifold flange, it is important to look at engine type, port design, bolt pattern, thickness and how the flange will be used in the specific build. Some flanges are made for specific engines or cylinder heads, while others are used in more customised solutions with turbo, custom manifold or other modifications. That is why it is important to choose the right flange so the parts fit together correctly from the start.
