Abstract
A muffler is capable of sufficiently reducing flow noise, discharge noise, vehicle noise, and cabin noise, preventing a pressure loss, and improving output power. The muffler has a muffler body, an upstream pipe that opens in the muffler body, and a downstream pipe that opens in the muffler body. An opening is formed in a side wall of the downstream pipe in the muffler body. The opening consists of many small holes arranged in an elongated area extending in an axial direction of the downstream pipe.
