Abstract: An exhaust aftertreatment system may include a housing, an aftertreatment device, and a cantilevered flow distributing element. The housing receives exhaust gas output from an engine and has a main body and an exhaust gas inlet that is angled relative to the main body. The flow distributing element is disposed within the housing upstream of the exhaust aftertreatment device and includes a baffle plate and a collar. The baffle plate is attached to an inner wall of the main body. The collar may include a plurality of first apertures, a downstream axial edge and an upstream axial edge. A portion of the downstream axial edge may abut an upstream-facing surface of the baffle plate. The baffle plate may have a plurality of second apertures extending through the upstream-facing surface. The collar may extend across and partially block at least some of the second apertures.
