A support system (120) for a fragile substrate (118) of an exhaust gas treatment device (110) includes a microporous, inorganic insulating layer (212, 322), which directly or indirectly engages at least a portion of the fragile substrate; and a flexible fibrous mounting mat (213, 323) which directly or indirectly engages at least a portion of said fragile substrate. The support system may support the fragile substrate of a catalytic converter, a diesel particulate trap filter, a selective catalyst reduction unit, or a NOx trap.
