Claims

[Scope of Claim for Utility Model Registration] 1. Exhaust for automobiles, etc., in which metal pipes 2 attached to multiple exhaust ports 1 of a multi-cylinder engine for each cylinder are assembled on the downstream side and connected to an exhaust pipe 4 via a flange 3. In the manifold, a collective case 5 of a plurality of pipes 2 is divided into a pipe-side case 5a and a flange-side case 5b of the exhaust pipe 4, and these are arranged in a similar manner within almost one plane. 2. A collection of exhaust manifolds in which the pipe side case 5a according to claim 1 is a wall surface that substantially matches the axis-perpendicular end surface of each pipe 2 to be inserted, and each pipe insertion hole 6 provided in the wall surface is substantially a perfect circle. Case.
