仕切り壁としたことを特徴とする排気集合管。 An exhaust manifold pipe that connects a plurality of exhaust branch pipes connected to each cylinder of a multi-cylinder engine and a single main exhaust pipe on the downstream side of the exhaust manifold pipes, the exhaust manifold pipes being combined radially. The downstream end of the short pipe is formed into a fan-shaped cross section, and the fan-shaped parts are welded together to form a cylindrical shape. The short pipes corresponding to the cylinders which are out of sequence in the order of explosion are arranged adjacent to each other, and a cut part cut into a chevron shape toward the upstream side is formed at the contact part of the two short pipes, and a cut part is formed in the shape of a chevron toward the upstream side. An exhaust manifold pipe characterized in that a partition wall is provided between the short pipes corresponding to the cylinders.
