Claims

[Scope of utility model registration request]

The upstream ends of the exhaust passages communicate with the exhaust ports of each cylinder of the multi-cylinder engine, and the downstream ends of the exhaust passages converge, and at least one pair of exhaust passages share an outer wall and are independent of each other via a partition wall. What is claimed is: 1. An exhaust manifold for a multi-cylinder engine, which is integrally formed so as to be adjacent to each other, wherein an outer wall surface of the exhaust manifold along an extension surface of the partition wall is raised.
