A V-type engine in which exhaust pipe arrangement is easily performed even in a V-type engine and that can be downsized even when a catalyst is installed. The engine has cylinders where pistons operate are arranged in a V-shape, a crankshaft driven by the driving of the pistons is disposed vertically, exhaust pipes communicating with exhaust openings in the respective banks of a cylinder head are included, merging exhaust pipes (exhaust pipes) in the respective banks are drawn toward a side of the cylinder head to be merged, and a catalyst holder that holds a catalyst is provided in a merge portion of the merging exhaust pipes. In this manner, since the merging exhaust pipes in the respective banks are merged and the catalyst holder is provided in this merge portion, exhaust gas from each bank can be purified by the catalyst.
