A system and method are disclosed for facilitating proper assembly of an exhaust system. The system includes a first modular exhaust treatment unit connectable to a second modular exhaust treatment unit. At one end, the first modular exhaust treatment unit includes a substantially continuous collar that integrates a first docking element therein. The second modular exhaust treatment unit includes a second docking element configured to engage the first docking element. When connected, the first and second docking elements operate to rotationally align and properly order the first and second modular exhaust treatment units.

System and method for facilitating proper assembly of an exhaust system

An apparatus and system are disclosed for ensuring proper assembly of an exhaust system. Ensuring proper assembly of an exhaust system is accomplished by providing an inflow exhaust subassembly for receiving engine exhaust, at least one intermediate subassembly that selectively mates and rotationally aligns with the inflow subassembly and receives engine exhaust therefrom, the at least one intermediate subassembly further configured to selectively mate according to a pre-selected alignment with an outflow subassembly, and the outflow subassembly configured to receive engine exhaust from the at least one intermediate subassembly. In certain embodiments, the at least one intermediate subassembly comprises a plurality of intermediate exhaust subassemblies each configured to selectively mate with adjacent subassemblies according to a pre-selected order and alignment.
