An exhaust gas aftertreatment device for a combustion engine includes an exhaust gas guide element that includes a dosage device for introducing a reduction agent into the guide element at a feed point and at least one interference element arranged upstream of the feed point, that introduces turbulences into the exhaust gas flow that is intermixed with the reduction agent. The guide element also includes a first guide portion, through which exhaust gas flows in a first flow direction, and a second guide portion, through which exhaust gas flows in a second flow direction that is opposite to the first flow direction. The first and second guide portions are fluidically connected with each other via a third guide portion, which redirects the exhaust gas from the first flow direction into the second flow direction. The feed point and the interference element are arranged in the third guide portion.
