ABSTRACT:
An automotive exhaust system incorporating an insulated exhaust pipe. The insulation is selected so that it is very efficient at relatively low temperatures, thereby allowing the exhaust gases to reach the light-off temperature of the catalytic converter in a short time, and less efficient at high temperatures, thereby maintaining the temperature of the exhaust gases below the level at which aging of the catalytic converter increases.
