In a cast iron exhaust manifold for cylinder internal combustion engines with one or more flanged pipe socket connections each assigned to a cylinder and at least one manifold, which forms a standard unit with the pipe socket connections opening into it, it is proposed according to the invention that the entire inner surface (10 to 12) of the pipe socket connections (1 to 3) and of the manifold have an outer anti-corrosion shell (10) composed of a coating fused on to the cast iron, which coating comprises the fused mass of an aqueous slip, applied in a thin layer to the inner surface, which slip has a ceramic frit with a high soft metal content. <IMAGE>
