Is It Normal for a New Car's Exhaust Pipe to Rust?

[StMadison]

Rusting of the exhaust pipe is actually a very normal phenomenon. Since the surface temperature of the exhaust pipe can become extremely high during operation, and manufacturers generally apply paint to it, the surface is essentially fully exposed to the elements. Over time, exposure to various acidic and alkaline substances, sewage, and other corrosive elements, combined with the high-temperature working environment, makes rust on the exhaust pipe inevitable. For daily maintenance, it is important to clean the drainage holes to prevent clogging. When driving in the rain or passing through deep water areas, water may seep into the exhaust pipe. Additionally, during car washing, avoid spraying water directly into the exhaust pipe opening. If water does enter the exhaust pipe, let the engine idle for more than ten minutes to allow the water to gradually evaporate.
