An aftertreatment component includes an inlet connector tube, an outlet connector tube, a chamber, a flow dissipater, and a substrate. The inlet connector tube receives exhaust gasses. The chamber is between the inlet connector tube and the outlet connector tube. The flow dissipater is positioned around the inlet connector tube and within the chamber. The flow dissipater receives the exhaust gasses from the inlet connector tube and includes a plurality of perforations. The plurality of perforations defines an open area of the flow dissipater. The open area of the flow dissipater is greatest proximate to the inlet connector tube and progressively decreasing proximate to the outlet connector tube. The substrate is positioned within the chamber and receives the exhaust gasses from the flow dissipater and provides the treated exhaust gasses to the outlet connector tube. The exhaust gases are expelled through the flow dissipater via the plurality of perforations.
