Abstract
A cast exhaust manifold for an engine is disclosed that is fastened to the engine by a number of independent flanges between each pair of which a spacer is positioned to produce an interference fit when the exhaust manifold is at ambient temperature. The use of independent flanges allow the exhaust manifold to expand when heated without creating high levels of internal stress and the spacers prevent undue distortion of the exhaust manifold when the exhaust manifold cools.
