Disclosed is an exhaust manifold connected to an internal combustion engine with a plurality of exhaust ports, equipped with a first upper shell member, a second upper shell member and a lower shell member. A first passage connected to at least one of the plurality of exhaust ports is formed superimposed upon the first upper shell member and the lower shell member; and a second passage is formed on the lower shell member, superimposed over the second upper shell member and flanking the first upper shell member such that at least one part thereof is exposed, and connected to at least one other of the plurality of exhaust ports. L'invention concerne un collecteur d'échappement relié à un moteur à combustion interne avec une pluralité d'orifices d'échappement, équipé d'un premier élément de coque supérieur, d'un deuxième élément de coque supérieur et d'un élément de coque inférieur. Un premier canal relié à au moins l'un de la pluralité d'orifices d'échappement est formé de manière à être superposé au premier élément de coque supérieur et à l'élément de coque inférieur. Un deuxième canal est formé sur l'élément de coque inférieur, de manière à être superposé au deuxième élément de coque supérieur et adjacent au premier élément de coque supérieur de telle sorte qu'au moins une partie de ce dernier soit exposée, et relié à au moins un autre de la pluralité d'orifices d'échappement.
