    摘要: An exhaust pipe arrangement for discharging exhaust from a combustion engine through an exhaust pipe is provided, particularly for a combustion engine with an exhaust gas aftertreatment system requiring high temperatures in one or more operational modes. The arrangement includes an end section terminated by an exhaust gas outlet. A diffuser section is provided in the exhaust pipe, the diffuser section having a first end in a distance from the outlet and a second end closer to the outlet is arranged in vicinity of the outlet, wherein at least one vane with an airfoil profile extends in an axial direction from the first end to the second end of the diffuser section.
