The exhaust pipe comprises an inlet pipe, an outlet pipe and a bend portion arranged between the inlet pipe and the outlet pipe. The bend portion comprises an inlet bend and an outlet bend, wherein a central bend portion defines an intermediate section of inlet bend and outlet bend and wherein the inlet bend and the outlet bend each cover 50 percent of the total bend angle covered by the bend portion. The central bend portion comprises a diameter, which is smaller than a diameter of the inlet bend and of the outlet bend in a bending plane. In addition a bend radius R of the bend portion varies along the bend portion such that a bend radius of the inlet bend is larger than a bend radius of the outlet bend.
