に背圧低減を可能とする排気音可変マフラ。 In a muffler, an exhaust gas distribution pipe consisting of a shell, an exhaust gas introduction pipe, and an exhaust gas discharge pipe is arranged, and an expansion chamber and a resonance chamber are formed between the exhaust gas distribution pipe and the shell. A communication hole leading to the expansion chamber is bored in the exhaust gas introduction pipe where the inlet and outlet of the installed resonance pipe face each other, and a cover operated by an actuator whose opening area is variable is provided in the communication hole of the exhaust gas introduction pipe. A variable exhaust sound muffler that changes the tone of the exhaust sound and makes it possible to reduce back pressure, characterized in that a valve that opens and closes by moving with the cover is provided near the outlet.
