What Causes Exhaust Pipe Abnormal Noise?

[LaEli]

Here are the reasons for exhaust pipe abnormal noise: Clogged catalytic converter: The function of the catalytic converter is to purify exhaust gases while reducing noise. Different vehicles have different catalytic converters with varying lengths, thicknesses, and densities of internal filters, depending on exhaust flow characteristics. Regular cleaning of the catalytic converter can eliminate abnormal noises from the exhaust pipe. Exhaust pipe aging: The exhaust pipe is connected to the engine via a flexible joint. Prolonged use may cause damage or aging of this flexible connection. Additionally, the exhaust pipe is mounted to the vehicle frame with several rubber rings - these should be checked for damage or aging. Finally, there are seals between the exhaust pipe and flexible joint, as well as between the flexible joint and engine, which should be inspected for wear. Water accumulation in exhaust pipe: For water accumulation issues, you can block the right exhaust pipe with a towel and rev the engine to expel water from the left pipe, or use a suction tube to remove the water.
