Abstract
A particulate filter includes first and second honeycomb substrates. An outlet face of a first substrate is positioned against an inlet face of a second substrate such that channels extending longitudinally through the substrates are aligned to form continuous channels. A continuous skin is joined to each of the substrates to form a unified substrate. A portion of the continuous channels are selectively plugged to form a wall flow filter.
