Abstract
An exhaust manifold for conducting heated exhaust gas from an internal combustion engine to an exhaust system. The exhaust manifold includes a preform and a metal layer enclosing the preform. The preform has an inner layer of silicon carbide, a middle layer of insulating material, and an outer layer to seal the middle layer from molten metal used to form the metal layer.
