Claim:
A muffler for a vehicle, comprising: a plurality of baffles fixed at a predetermined distance in a longitudinal direction of a muffler housing within the muffler housing; an exhaust gas inflow pipe having an inlet thereof connected with the muffler through a front of the muffler housing and an outlet thereof fixed inside the muffler housing through a first of the baffles; an intermediate pipe fixed through a second of the baffles in the muffler housing such that an inlet thereof is positioned in line with the outlet of the exhaust gas inflow pipe in one chamber defined by the first and the second of the baffles; and a plurality of exhaust gas outflow pipes having an inlet thereof positioned with the outlet of the intermediate pipe in another chamber defined by the second and a third of the baffles such that the exhaust gas passing through the intermediate pipe is directly discharged outside the muffler housing though the plurality of exhaust gas outflow pipes, and an outlet thereof protruding outward through the muffler housing such that the discharging direction of the exhaust gas though the plurality of exhaust gas outflow pipes does not meet the input direction of the exhaust gas into the intermediate pipe, without passing through at least one of the baffles; wherein a longitudinal axis of the plurality of exhaust gas outflow pipes and a longitudinal axis of the intermediate pipe are substantially perpendicular to each other.
