An exhaust treatment packaging apparatus, system, and method includes an elongate exhaust gas passage comprising an inlet for the entrance of flowing exhaust gases and an outlet for the exit of the gases. A catalytic device comprising an inlet and an outlet completely or partially overlaps the passage to reduce the length required for the system. The passage outlet is disposed adjacent the catalytic device inlet, and a flow connector connects the passage outlet to the catalytic device inlet. A particulate filter or other treatment device may be substituted for or added to the catalytic device. A doser disposed upstream of the passage doses an additive which evaporates, mixes, or otherwise undergoes change in the passage before reaching the catalytic device.
