The car has been used for a long time, and many have encountered the phenomenon of rust on the exhaust pipe. Some have a large surface area of rust, while others have localized rust with a hole in the rust. So what should I do if the exhaust pipe rusts? Is there a way to prevent rust?

The car has been used for a long time, and many have encountered the phenomenon of rust on the exhaust pipe. Some have a large surface area of rust, while others have localized rust with a hole in the rust. So what should I do if the exhaust pipe rusts? Is there a way to prevent rust? Do we need to replace the rusted parts? Today we will talk about these issues with exhaust pipes.

       Exhaust Pipe (1)

The exhaust pipe has several functions. Firstly, it exhausts the exhaust gas generated by combustion to the rear of the car, so that the exhaust gas does not enter the driver's cabin during driving. Secondly, there is a muffler on the exhaust pipe, which can reduce the noise generated by engine combustion. Thirdly, it can generate a certain amount of back pressure, which is beneficial for more complete combustion. The lifespan of exhaust pipes varies, some break down in five or six years, while others only break down in a decade or so, which is closely related to their own quality. Some car series are particularly prone to breakage, while others are less prone to breakage.

       If the exhaust pipe starts to rust, basically you can only watch it get more and more rusty, and there is no way to do rust prevention treatment because the temperature of the exhaust pipe is very high, and the surface cannot be sprayed with rust prevention materials. However, the rust damage to the exhaust pipe does not gradually spread from the outside to the inside, but rather from the inside and gradually spreads to the outside. Because places with damp environments are prone to rust, as long as it doesn't rain, the surface of the exhaust pipe is always dry and there won't be too much rust. Even if the rust is only slight, although the area is large, the depth is not deep. So there's no need to worry about rusting on the surface, it won't cause serious damage. And if the exhaust pipe remains moist for a long time, water will be generated in the exhaust pipe as long as driving, and some cars can also clearly see flowing water. After parking, it doesn't dry for a long time, so it starts to rust from the areas with more water inside, and the rust becomes more severe until it reaches the surface and forms a large hole.

     Rust on the exhaust pipe is inevitable. If the rust is damaged, some areas can be repaired, while others can only be replaced. To have a long lifespan, it is necessary to replace the exhaust pipes with good quality ones, and there will be no problems for more than ten years. Some exhaust pipes are very thin and the materials used are not good, which will rust faster. In addition, if there is water accumulation in the exhaust pipe and you hear a purring sound, it should be dealt with in a timely manner. Usually, a small hole is made at the lowest point of the exhaust pipe to allow water to flow out, which can also reduce water accumulation and extend the lifespan of the exhaust pipe.

     If the exhaust pipe rusts and damages a large hole, what is the impact of not replacing it? It is common to rust large holes in the muffler at the tail end of the exhaust pipe. If not replaced, it will not have any impact on the vehicle itself, but the noise will become very loud. The sound of the gas door is even louder, like the sound of a sports car, but it doesn't sound so pleasant. It sounds like a broken car. If you don't mind, you can tolerate the noise and don't want to change it. However, most people will choose to replace it, and the cost is not high. If the part is damaged, it can be replaced.
