Abstract:
A vehicle exhaust device includes a muffler body that has an interior space divided into a plurality of expansion chambers by a partition wall, and an exhaust control valve that switches an exhaust passage in the muffler body. The exhaust passage includes a first exhaust passage and a second exhaust passage. The first exhaust passage connects an upstream end and a downstream end of the muffler body straight. The second exhaust passage passes through the plurality of expansion chambers via a connecting pipe that connects the plurality of expansion chambers. A center of the first exhaust passage is located above a center of the muffler body in a vehicle upper-lower direction, and the second exhaust passage is located below the first exhaust passage.
