摘要： To provide an exhaust device capable of suppressing exhaust interference generated between a front cylinder exhaust pipe and a rear cylinder exhaust pipe, and further substantially equalizing an exhaust performance of front and rear cylinders. An exhaust device of a vehicle provided with a V-engine 5 having a front cylinder 52 and a rear cylinder 53 has a muffler 93 arranged in a rear part of the vehicle, a front cylinder exhaust pipe 91 connected to a front surface of the front cylinder 52, a rear cylinder exhaust pipe 92 connected to a rear surface of the rear cylinder 53, a collecting pipe 94 collecting the front cylinder exhaust pipe 91 and the rear cylinder exhaust pipe 92, and a downstream exhaust pipe 95 reaching from the collecting pipe 94 to the muffler 93. Total length of the front cylinder exhaust pipe 91 and total length of the rear cylinder exhaust pipe 92 are substantially the same.
