Claims

[Scope of Claim for Utility Model Registration] Each exhaust manifold communicating with the exhaust outlet of each cylinder according to the ignition order in a multi-cylinder engine is merged into a plurality of groups of exhaust manifold pipes, and the exhaust manifolds of the plurality of groups are connected to each other. In an exhaust pipe device in which exhaust pipes are assembled into one exhaust pipe on the downstream side, a flange portion that connects the plurality of exhaust pipes in the plurality of groups to one exhaust pipe is provided inside a flange portion that corresponds to the plurality of exhaust pipes in the plurality of groups. An exhaust pipe device for a multi-cylinder engine, characterized in that a partition plate is provided to form an exhaust passage in the single exhaust pipe, and the length of the exhaust manifold pipe is substantially increased. .
