초록

An exhaust manifold for conducting the heated exhaust gas from an internal combustion engine. The exhaust manifold has a thin noncast metal inner layer, a thicker sheet metal outer layer, and a layer of insulating material, preferably ceramic beads, between the inner and outer layers. The method of making the exhaust manifold is also disclosed. The exhaust manifold is damped, insulated, and permits quicker light off of the catalytic converter.
