Claims

[Scope of utility model registration request]

A plurality of parallel branch pipe parts are connected to a collecting pipe part, and a flange part is provided at the tip of each branch pipe part for mounting the tip part on the engine, and the part is substantially flush with the mounting surface of the flange part. In an exhaust manifold in which flange parts are connected by a series of bridge parts, the bridge part has a short length on the side that is in close contact with the engine and a surface in a direction perpendicular to the axis of the branch pipe part. An exhaust manifold characterized in that it is formed with a cross-sectional shape having a larger ratio of the length of the parallel opposite collecting pipe side.
