Normal. When the exhaust pipe is working, the surface temperature is very high, and most manufacturers don't paint it, which is basically bare leakage. This phenomenon basically happens in every car in use. Because the exhaust pipe is exposed for a long time, it will be damaged by various acid and alkali substances and ground sewage. In addition, it is in a high temperature working environment. After a long time, the exhaust pipe will definitely rust. Rusting of exhaust pipe is inevitable, so we should pay more attention to it in normal use. Some car owners drive 40,000 to 50,000 kilometers, which is basically fine. Some car owners only drive 10,000 kilometers, and most exhaust pipes are badly rusted. In fact, the materials are basically the same, mainly because of the different ways of using cars. In the normal use of vehicles, we must pay attention to prevent driving in particularly bad road conditions, and the chassis needs to be cleaned immediately, especially when passing through acid and alkali ground and parking, and pay attention to the parking environment. Only by paying attention to these small aspects will the service life of the exhaust pipe be extended for a very long time. Click to view the rest _ Is the automobile exhaust pipe rusted normally?
