マニホールド。 It has the same number of branch pipes as the number of exhaust discharge ports of the multi-cylinder engine to be installed, and the openings at one end of each branch pipe are arranged at intervals corresponding to the intervals of the exhaust discharge ports, and the other ends of each branch pipe are arranged at intervals corresponding to the intervals of the exhaust discharge ports. In an exhaust manifold that is used as an exhaust pipe connection part for merging and connecting the ends of one exhaust pipe, the exhaust pipe is located in a part of the plurality of pipes that undergoes a large amount of deformation due to thermal expansion. An exhaust manifold characterized in that elastically deformable bulges are formed in the middle of the branch pipes, extending over the entire circumference of the branch pipes.
