2. Description of the Related Art Generally, a muffler applied to an exhaust system in an automobile can function to lower the exhaust noise by lowering the temperature and pressure of the exhaust gas discharged from the engine.

Such a muffler can be configured to divide the inside of the tubular member having a predetermined shape into several spaces so that the exhaust gas can reduce the interference, the pressure fluctuation, the exhaust temperature, and the like of the sound waves passing through the barriers, thereby gradually reducing the noise .

Accordingly, in order to discharge the condensed water as soon as possible, the exhaust pipe installed downward toward the ground may be installed at the rear end of the muffler to generate condensed water by the condensation phenomenon in the process of cooling the exhaust gas at high temperature inside the muffler have.

On the other hand, in recent years, vehicles employing a GDI (Gasoline Direct Injection) engine have been increasing. In the case of a vehicle equipped with such a GDI engine, too much soot may be generated in the exhaust gas.

The soot inside the exhaust gas is mixed with the condensed water formed inside the muffler, and the resulting condensed water can be changed to black.

However, in the vehicle having the GDI engine as described above, the exhaust pipe to which the conventional downwardly installed structure is applied is configured such that black condensed water mixed with soot is quickly discharged to the ground when the vehicle is idling, Which may cause a problem of environmental pollution.
