Motorcycle muffler is an indispensable part in the history of motorcycle development, and the history of motorcycle muffler is as long as that of motorcycle.
After the engine does work, it is followed by the exhaust stroke. Exhaust is to exhaust the exhaust gas in the cylinder. Because the exhaust gas at this time is high temperature and high pressure, it will be very noisy if it is discharged directly from the exhaust pipe. Simply put, the function of the muffler is that the airflow discharged by the engine passes through the perforated pipe and baffle in the muffler and rolls back repeatedly, so that the noise is gradually attenuated and the purpose of noise elimination is achieved.
