Abstract
A method of manufacturing an exhaust pipe includes inserting a cover member into an approximately circular opening provided at a first end of a first exhaust pipe. An inner circumferential portion of the cover member has a ring shape with a central axis. When the cover member is inserted into the opening, its outer circumferential surface faces a first inner circumferential surface of the exhaust pipe. A maximum width of the inner circumferential portion is equal to, or greater than, a radius of a circumference of the opening. A minimum width of the inner circumferential portion is smaller than the radius. A circumferential length of the outer circumferential surface is shorter than the length of the circumference of the opening.
