An exhaust assisted pipe assembly including an outer portion having an opening for receiving dosed reductant from a dosing module and an inner portion disposed within the outer portion. The inner portion defines a main flow path for receiving a first portion of a fluid from an upstream source, and the inner portion and the outer portion cooperatively define a first flow path and a second flow path. The first flow path is configured to direct a second portion of the fluid from the upstream source past the opening for receiving dosed reductant and into the main flow path to increase momentum of the dosed reductant into the main flow path. The second flow path is configured to direct a third portion of the fluid from the upstream source toward the dosed reductant to decrease the momentum of the dosed reductant in the main flow path.
