したことを特徴とする可変型消音器。 A box body surrounds a pair of exhaust pipes in the middle, and a plurality of small holes are bored in the middle of one of the exhaust pipes to guide exhaust gas into the box body, and the exhaust pipe is configured as a perforated pipe. A neck pipe that guides exhaust gas into the box body is arranged in the middle of the other exhaust pipe, and both ends of one exhaust pipe are connected to the other exhaust pipe to connect the pipes of each exhaust pipe, A control valve that opens and closes the pipe of each exhaust pipe depending on the operating condition of the engine is installed in the middle of the pipe that leads exhaust gas to the box body among the pipes of each exhaust pipe. The engine is characterized in that when the engine speed is low, the line of the porous pipe is closed and the line of the other exhaust pipe is opened, and when the engine speed is high, the line of the porous pipe is opened and the line of the other exhaust pipe is closed. Variable silencer.
