Title: Exhaust manifold

Abstract: An exhaust manifold for a supercharged internal combustion engine which includes inner pipes carrying the exhaust gases from the engine and a water-cooled housing surrounding the inner pipes at a predetermined spacing. The housing is mounted to exhaust gas flanges of the internal combustion engine by way of water-cooled intermediate flanges. The housing includes an opening on a side thereof facing away from the engine with the opening extending approximately over the entire length of the housing and being closable in a gas-tight fashion by a cover. The housing is bolted to the exhaust gas flanges from the inside thereof and the inner pipes are formed of individual pipe segments assembled with plug connections with the length of the various pipe segments corresponding approximately to the cylinder spacing of the internal combustion engine.
