An exchanger has a bundle of exhaust has pipes, and a bypass pipe (10) respectively flows into a common exhaust gas inlet area. An exhaust gas valve is arranged in the inflow area for controlling the flow of exhaust gas through the pipe bundle or the bypass pipe. The bypass pipe is designed as a high-grade steel pipe with a jacket (11) made of high-temperature stable plastics and is arranged in a coolant flowing housing. A cross-sectional area of the high-grade steel pipe is oval. |
