An exhaust manifold for a vehicle engine and a manufacturing process to prevent corrosion of the manifold during shipping and storage. The manifold includes a manifold body having a plurality of arms corresponding to the exhaust ports of the engine and a collector chamber for directing the exhaust gasses to the vehicle exhaust system. Attached to the ports of the body are flanges to facilitate connection of the manifold to the engine. The flanges are manufactured of carbon steel and includes apertures to receive mounting flanges. To prevent corrosion of the flanges, the flanges are subject to a process of ferritic nitro carburization which inhibits the formation of iron-oxide.
