A decomposition chamber for an exhaust aftertreatment system includes an inlet tube, a selective catalytic reduction (SCR) catalyst member, a mixing collector wall, a distribution cover, and a shunt tube. The inlet tube is configured to receive exhaust gas. The mixing collector wall includes a mixing assembly flow aperture. A distribution cover is coupled to the inlet tube and configured to receive exhaust gas from the inlet tube. A shunt tube is coupled to the mixing collector wall. A shunt tube separates the dispensing cap from the mixing assembly flow aperture. The shunt tube includes a first shunt tube inlet aperture configured to receive exhaust gas from the distribution cover. The shunt outlet orifice is configured to provide exhaust gas to the mixing assembly flow orifice. 一种用于排气后处理系统的分解室，包括入口管、选择性催化还原(SCR)催化剂构件、混合收集器壁、分配盖和分流管。入口管被配置为接收排气。混合收集器壁包括混合组件流动孔。分配盖耦合到入口管并被配置为接收来自入口管的排气。分流管耦合到混合收集器壁。分流管将分配盖与混合组件流动孔分开。分流管包括第一分流管入口孔，第一分流管入口孔被配置为接收来自分配盖的排气。分流管出口孔被配置为将排气提供给混合组件流动孔。
