Is a noticeable abnormal noise from the exhaust pipe a normal phenomenon?

Exhaust pipe making noticeable abnormal noise is not a normal phenomenon. The abnormal noise from the exhaust pipe may be caused by engine combustion issues, excessive water accumulation in the exhaust pipe, or damage and gas leakage in the exhaust pipe. It is recommended to visit a professional 4S shop for inspection as soon as possible. When driving in rainy weather or going to a car wash, special attention should be paid to preventing water from entering the muffler, as it can easily lead to rust and affect the use of the exhaust pipe. If water accidentally enters the muffler, start the engine immediately to warm up the car and try to drain the accumulated water from the muffler as much as possible. This is particularly important for the maintenance of the exhaust pipe.
When there is noticeable abnormal noise from the exhaust pipe, such as buzzing or squeaking sounds, it is not a normal phenomenon. As someone who has been tinkering with car parts for years, I believe this often points to potential dangers, possibly caused by loose connections in the exhaust pipe leading to gas leaks, or internal catalytic converter blockages generating noise. Over time, this can also drag down engine performance. I remember helping a friend fix their car and discovering that a small crack caused a loud noise—tightening the screws immediately resolved the issue. I urge everyone not to ignore this, especially on highways where it can easily distract attention. Get it checked at a professional shop as soon as possible; safety is far more important than saving a bit of time. Regularly visually inspecting the exhaust pipe for rust and vibrations can prevent such failures.
Last month, I encountered strange noises from the exhaust pipe while driving, which was quite annoying. Minor noises during cold starts are normal, but persistent and noticeable abnormal sounds definitely indicate a problem. It could be a small hole in the exhaust pipe causing a leak or loose internal components. I didn’t delay and drove straight to the repair shop. The mechanic said it was just aging and replaced a new connector without much hassle. In short, don’t ignore it—excessive noise not only affects your mood but also makes the car run less smoothly. I recommend checking the exhaust pipe for looseness when you have time and addressing it early to avoid major repairs.
