In an exhaust system for a motorcycle with a V-type engine mounted thereon, the front cylinder exhaust line has a first exhaust pipe arranged to the front while the rear cylinder exhaust line has a second exhaust pipe arranged to the rear. The first and second mufflers are attached to one side of the vehicle body with the second muffler arranged in parallel to and above the first muffler and shifted behind with respect to the first muffler. The first expansion chamber of the first muffler and the first expansion chamber of the second muffler are connected to be in communication with each other by means of a communicating pipe. One end of the communicating pipe is joined to the peripheral surface of the muffler cylinder corresponding to the first expansion chamber of the first muffler while the other end is connected in parallel with the second exhaust pipe to the front-end entrance port of the second muffler corresponding to the first expansion chamber of the second muffler.
