What causes the exhaust pipe noise in Besturn B50?

[GraceDella]

The causes of exhaust pipe noise in Besturn B50 are as follows: Clogged three-way catalytic converter: The function of the three-way catalytic converter is to reduce noise while purifying exhaust gases. For different vehicles, the three-way catalytic converters vary in length, thickness, and the density of the internal filter, depending on the exhaust flow. Regular cleaning of the three-way catalytic converter can eliminate the noise from the exhaust pipe. Aging exhaust pipe: The exhaust pipe is connected to the engine via a flexible joint, which may become damaged or worn out after prolonged use. Additionally, the exhaust pipe is fixed to the chassis by several rubber rings. It is advisable to check whether these rubber rings are damaged or have aged. Lastly, there are seals between the exhaust pipe and the flexible joint, as well as between the flexible joint and the engine. These seals should be inspected for any damage. Water accumulation in the exhaust pipe: To address water accumulation in the exhaust pipe, you can block the right exhaust pipe with a towel and then rev the engine to expel the water from the left pipe. Alternatively, you can use a straw to remove the water.
