What is the treatment method for a rusted exhaust pipe?

[JessicaAnn]

The treatment method for a rusted exhaust pipe is: use a lift to raise the car, then spray rust remover on the exhaust pipe to prevent it from rusting again. The functions of the exhaust pipe are: 1. Reduce environmental pollution. The exhaust pipe has an internal purification device, with a three-way catalytic converter that effectively purifies harmful gases in the exhaust; 2. Ventilation and exhaust. The car exhaust pipe operates in a cycle of intake, compression, power, and exhaust. Without the exhaust pipe, the car would not function; 3. Reduce noise. The exhaust pipe is equipped with a muffler, which lowers the car's noise. The principle is to use multiple channels to divert airflow, causing friction and collisions between the diverted flows, gradually reducing the airflow speed and repeatedly cycling to lower noise.
