The method includes detecting operating conditions of an engine and operating a valve that is disposed on a line bypassing a catalyst unit based on the operating conditions such that exhaust gas bypasses the catalyst unit. The operating conditions include a vehicle speed, an engine rotation speed, a fuel injection amount, an accelerator pedal signal, a coolant temperature, or a lambda value of exhaust gas.
