Claims

[Scope of utility model registration request]

A plurality of primary exhaust pipes whose proximal ends are connected to the exhaust port of each cylinder of a multi-cylinder engine are connected to one end and gathered together, and a secondary exhaust pipe is installed at the other end to reduce the number of exhaust passages. In a collective exhaust pipe of a multi-cylinder engine that connects a multi-cylinder engine, a single plate is bent and a partition part dividing the inside of the collective exhaust pipe into two is placed in the center on both side edges of the partition part and separated from each other from each edge. a main joint plate forming two outer wall portions that are continuous in the direction and respectively constitute one quarter of the outer wall of the collective exhaust pipe; A collective exhaust pipe for a multi-cylinder engine, characterized in that it is comprised of two sub-joint plates that are arranged to face each outer wall of a main joint plate and form an exhaust passage between each outer wall.
