An exhaust silencing device connected to an exhaust system of an engine is provided in which two outlet pipes that have at an upstream end thereof an opening portion opening within the silencer main body and that discharge exhaust gas within the silencer main body to an outside thereof are disposed within the silencer main body along a bottom thereof so that the distances thereof from the lowest part of the bottom are substantially equal, and the opening portion of one outlet pipe is directed further toward the bottom of the silencer main body than is the opening portion of the other outlet pipe. Such exhaust silencing device efficiently discharges to the outside the condensed water building up within the silencer main body so as not to impair an effect in reducing exhaust resistance by providing two outlet pipes that guide the exhaust gas to the outside.
