Exhaust gas flowing through the converter is hot and the chemical reactions within the converter adds additional heat. Most converters operate in the 600 to 900 degree Fahrenheit range. When raw fuel enters a converter such as with an engine misfire the temperature can get significantly higher and quickly damage the converter.
