The first decomposition chamber is configured to receive an exhaust gas. The first dosing module is coupled to the first decomposition chamber and configured to provide a first treatment fluid into the first decomposition chamber. The first conversion catalyst member is configured to receive a mixture of the first treatment fluid and the exhaust gas, from the first decomposition chamber. The second decomposition chamber is configured to receive the exhaust gas from the first conversion catalyst member. The second dosing module is coupled to the second decomposition chamber and configured to provide a second treatment fluid into the second decomposition chamber.
