What is the general temperature of an exhaust pipe?

[BenjaminMarie]

Generally, at an exhaust pressure of 20kg, the exhaust temperature is around 90 degrees. Below is relevant information about exhaust pipe temperatures: 1. Depending on the vehicle model: The outlet temperature of the final exhaust pipe varies based on different vehicle models, the length of the exhaust pipe, and the number of mufflers. Typically, the exhaust pipe temperature of small family cars ranges between 30–120 degrees. Some modified cars can even have exhaust pipes that emit flames, with outlet temperatures reaching several hundred degrees. 2. Exhaust pipe length: The longer the exhaust pipe, the lower the outlet temperature at the tail end. Additionally, higher engine speeds result in higher exhaust temperatures. At idle, the outlet temperature is only around 30–50 degrees. 3. Engine temperature: The temperature from the engine to the exhaust manifold is 800–900 degrees. After passing through the front catalytic converter, it drops to 600–700 degrees. The temperature at the middle section of the muffler decreases to about 200–300 degrees, while at the tail section of the muffler, it is around 150 degrees. After cooling through the muffler baffle, the exhaust gas temperature is slightly above ambient, about 20–50 degrees.
