A method of fabricating a decomposition conduit with an in-line static mixer, the method including molding a decomposition conduit housing around a sand core by inserting molding material into a cavity between a decomposition conduit housing mold and the sand core, where the sand core includes a static mixer and, where the act of molding the decomposition conduit housing is operative to mount the static mixer to the molded decomposition conduit housing.

Decomposition conduit fabrication method

An exhaust aftertreatment device has a unitary cast inlet that is configurable to have a 90&#xb0; or 180&#xb0; entry of combustion gasses relative to flow through tubular elements housing a diesel oxidization catalyst and a diesel particulate filter. The cast component provides the primary structural support for a tubular element connected to the casting element.
