PROBLEM TO BE SOLVED: To provide an exhaust system for a motor cycle to realize an effective exhaust pipe layout.SOLUTION: Along the longitudinal direction of a vehicle, there is mounted a V-shaped engine arranged in the longitudinal direction of a vehicle with front and rear cylinders being arrayed in a V-shape. On the exhaust downstream side of an assembly 13 of an exhaust pipe 11 of a front cylinder 126 and an exhaust pipe 12 of a rear cylinder 127, there is arranged a catalyst device 14, and a breathing tube 22 for communicating the exhaust pipe 11 of the front cylinder 126 and the exhaust pipe 12 of the rear cylinder 127 passes through a space S between the exhaust pipe 12 of the rear cylinder 127 and the catalyst device 14.
