Is the End of a Car's Exhaust Pipe Hot?

[MacDawson]

The end of a car's exhaust pipe is hot but generally below 80 degrees Celsius. Here are the relevant details: 1. Front section of the exhaust pipe: The temperature ranges between 350-400 degrees Celsius, which is beneficial for the operation of the catalytic converter. The longer the exhaust pipe, the lower the temperature at the tail end. Additionally, higher engine speeds result in higher exhaust gas temperatures. When the vehicle is idling, the outlet temperature is only around 30 to 50 degrees. 2. Outlet temperature: The temperature at the outlet of the final tailpipe varies depending on the vehicle model, the length of the exhaust pipe, and the number of mufflers. Generally, for small family cars, the exhaust pipe temperature ranges between 30-120 degrees Celsius. Some modified cars with exhaust pipes that can emit flames may have outlet temperatures reaching several hundred degrees.
