outer pipe 2 is achieved in order to account for the demand for low heat losses the exhaust gas conduction component is constructed as a double line isolated with an air gap with an outer pipe 2 and an inner pipe 8 the inner pipe 8 extends across the entire length of the exhaust gas conduction component 1 wherein the inner pipe 8 ends approximately flush with the outer pipe 2 at the corresponding end section 6 7 apart from the joints 9 11 12 the inner pipe 8 does not contact the outer pipe and is arranged with an annular gap coaxial to the outer pipe 2 at the joints 9 11 12 the inner pipe 8 is connected rigidly to the outer pipe 2 along a peripheral line here one joint 9 is provided approximately in the center and two additional joints 11 12 are provided at each end the joints are constructed for example as uninterrupted peripheral weld seams however other types of joining technology could also be used which will be discussed in detail farther below due to the described embodiment in each half of the exhaust gas conduction component 1 there is an annular air gap that is continuous from each end region up to the middle and this air gap prevents to a large degree heat transfer from the interior of the exhaust gas conduction component 1 to the outer pipe 2 and thus heat dissipation to the surroundings because there is only a small contact zone between the inner pipe 8 and the outer pipe 2 at the joints 9 11 12 in comparison with the total dimensions the heat losses due to heat.
