How high is the temperature of the automobile exhaust pipe?

The maximum temperature of automobile exhaust pipe can reach 800- 1000 degrees, specifically: 1. In general, the exhaust temperature of small family cars is between 30- 120 degrees. 2. After lengthening: the longer the length of the exhaust pipe, the lower the outlet temperature of the tail, the higher the engine speed and the higher the exhaust temperature. When idling, the vehicle outlet temperature is only 30 to 50 degrees. The exhaust temperature from the engine to the exhaust manifold is 800~900 degrees, and the temperature of the preceding three-way catalyst is 600~700 degrees. The temperature of the muffler is basically 200~300 degrees, the temperature of the rear muffler is about 150 degrees, and the exhaust gas cooled by the muffler partition is slightly 20~50 degrees higher than the normal temperature.
