An exhaust pipe structure is the exhaust pipe structure with a catalyst converter provided immediately close to an engine and includes a plurality of exhaust passages and a collecting portion. The collecting portion arranged between the first exhaust passage provided at an end side and a second exhaust passage includes a first guiding portion, a second guiding portion, and a rotating/guiding portion. The exhaust gas introduced from the first exhaust passage and the exhaust gas introduced from the second exhaust passage are guided obliquely downward by the first guiding portion and the second guiding portion, respectively, and are then rotated and guided by the rotating/guiding portion in respective directions opposite to each other to flow toward the catalyst converter. |
