Abstract
An exhaust line for an exhaust system of an internal combustion engine having a catalytic converter, the exhaust line being located upstream of the catalytic converter with respect to the flow direction of exhaust. The exhaust line has an externally applied heat-conducting layer preferably made of a metallic material and an internally disposed insulating layer made of a heat-insulating material. The insulating layer and the heat-conducting layer are connected directly and forcewise with one another. The layer thickness of the insulating layer is less than 2 mm, the specific heat capacity c of the insulating layer is less than 10,J/(m,h), and the heat diffusivity &kgr; of the insulating layer is less than 0.01 cm,/s.
