A decomposition chamber for an exhaust gas aftertreatment system includes an inlet tube, a selective catalytic reduction (SCR) catalyst member, a mixing collector wall, a distribution cap, and a dividing tube. The inlet tube is configured to receive exhaust gas. The mixing collector wall includes a mixing assembly flow aperture. The distribution cap is coupled to the inlet tube and configured to receive the exhaust gas from the inlet tube. The dividing tube is coupled to the mixing collector wall. The dividing tube separates the distribution cap from the mixing assembly flow aperture. The dividing tube includes a first dividing tube inlet aperture that is configured to receive the exhaust gas from the distribution cap. The dividing tube outlet aperture is configured to provide the exhaust gas to the mixing assembly flow aperture.
