Why Does the Exhaust Pipe of a New Car Rust?

[LaEdward]

The rusting of a new car's exhaust pipe is due to material issues or the car frequently driving at low speeds, preventing the engine from warming up sufficiently. Here are the relevant explanations: 1. Material: It is directly related to the manufacturing materials used, and different brands and models may use varying materials, which can significantly affect their rust and corrosion resistance. 2. Exhaust Pipe: The car's exhaust pipe plays a role in reducing vibration and noise, as well as extending the lifespan of the exhaust muffler system. The main material of the exhaust pipe is stainless steel. For most cars, since the exhaust gases leave the engine under high pressure, the noise generated can be overwhelming. The primary function of the exhaust pipe is to reduce this noise, with an internal muffler significantly lowering the car's noise levels.
