PROBLEM TO BE SOLVED: To provide an exhaust pipe for a saddle riding type vehicle capable of easily ensuring excellence of exhaust discharge owing to pulsation effect and a reduction in ventilation resistance.SOLUTION: An exhaust pipe for a saddle riding type vehicle of a double pipe structure includes an inner pipe 21 to be built in an outer pipe 22 with a predetermined clearance interposed therebetween. The diameter of a downstream side end portion of the inner pipe 21 is enlarged, and the outer pipe 22 is formed longer by a predetermined length toward the downstream side than an enlarged diameter part 27 of the inner pipe 21. The diameter of an exhaust flow part for exhaust gas in the exhaust pipe is configured to be enlarged on the way. |
