What causes the bubbling sound in the Skoda Yeti's exhaust pipe?

[DiGrant]

Skoda Yeti's exhaust pipe producing a bubbling sound may be caused by a blocked drain hole in the exhaust pipe, leading to condensed water accumulating inside the pipe while driving, which creates the bubbling noise. More information about the exhaust pipe is as follows: 1. The exhaust pipe generally includes the front exhaust pipe and the rear exhaust pipe. 2. The exhaust pipe is part of the engine's exhaust system, which mainly consists of the exhaust manifold, the exhaust pipe, and the muffler. The three-way catalytic converter, usually installed to control the engine's pollutant emissions, is also part of the exhaust system. 3. It is actually a normal phenomenon for a car's exhaust pipe to drip water, indicating that the car's engine is fully combusting, and it has nothing to do with the exhaust pipe.
