Abstract
An exhaust treatment device includes an inner shell, an outer shell and insulation material positioned between the inner shell and the outer shell. An inlet tube has an end in communication with a cavity defined by the inner shell. A substrate for treating engine exhaust is positioned within the inner shell. A baffle plate includes a plurality of apertures positioned such that the exhaust passes through the apertures prior to entering the substrate. The baffle plate supports an end of the inner shell and the inlet tube.
