What is the function of adding an exhaust pipe to a car?

[DeLucia]

Car exhaust pipes play a role in reducing vibration and noise for the car body, as well as extending the lifespan of the exhaust muffler system. More information about car exhaust pipes is as follows: 1. Car exhaust pipes are mainly used for light vehicles, mini vehicles, and buses. Their structure consists of a double-layer corrugated pipe covered with a steel wire mesh sleeve, with clamping rings on both straight end sections. To achieve better noise reduction effects, expansion joints or mesh sleeves can be installed inside the corrugated pipe. 2. The main material of car exhaust pipes is stainless steel SUS304, while the clamps and connecting pipes can be made of stainless steel or aluminized steel. 3. The working principle of car exhaust pipes: By using multiple channels to divert the airflow, these diversions create friction and collisions between them, gradually reducing the flow velocity of the airflow. This cycle repeats, ultimately allowing the exhaust gas to be discharged through the car's exhaust pipe, thereby reducing noise.
