To provide an exhaust device for a saddle-ride type vehicle which enables compact arrangement while securing the length of an exhaust passage.SOLUTION: An exhaust device 35 of a two-cylinder engine E mounted on a saddle-ride type vehicle includes an exhaust pipe 24 extending downward in front of the engine E from an exhaust port 20a of each of cylinders, a collecting pipe 26 in which the exhaust pipes 24 are collected, a catalyst pipe 30 which is arranged in the downstream side of the collecting pipe 26 and in which a catalyst converter 28 is stored, and a muffler 34 which is located in the downstream side of the catalyst pipe 30. The catalyst pipe 30 has a front end 30a connected to a downstream end 26b of the collecting pipe 26, is extended in a longitudinal direction of the vehicle, and has a rear end 30b connected to the muffler 34. The muffler 34 is formed to have the longitudinal dimension and the vehicle width dimension larger than those of the catalyst pipe 30, and muffles exhaust G. Downstream ends 24b of the two exhaust pipes 24 are aligned in the longitudinal direction.SELECTED DRAWING: Figure 1
【課題】排気通路の長さを確保しつつ、コンパクトに配置することができる鞍乗型車両の排気装置を提供する。【解決手段】鞍乗型車両に搭載された2気筒エンジンEの排気装置35であって、各気筒の排気ポート20aからエンジンEの前方を下方に延びる排気管24と、排気管24が集合する集合管26と、集合管26の下流側に配置されて触媒コンバータ28が収納された触媒管30と、触媒管30の下流側に配置されたマフラ34とを備えている。触媒管30は、前端部30aが集合管26の下流端部26bに接続され、車両の前後方向に延び、後端部30bがマフラ34に接続されている。マフラ34は、その前後方向寸法および車幅方向寸法が触媒管30よりも大きく形成され、排気Gを消音する。2本の排気管24の下流端部24bが、前後方向に並んでいる。【選択図】図1
