The present disclosure relates to an exhaust aftertreatment device (30) having a core (18) and an outer housing (40) and a mounting layer (50) positioned between the core (18) and the outer housing (40). The core has an upstream end face (20) and a downstream end face (22). The mounting layer (50) and the housing (40) have main portions (52) that extend from the upstream end face (20) to the downstream end face (22) of the core (18). The mounting layer (50) and the housing (40) also include end portions (40a, 40b) that overlap the end faces of the core (18) to retain the core within the housing (40). The end portions (50a, 50b) of the mounting layer (50) are compressed against the end faces of the core (18) by the end portions (40a, 40b) of the housing (40).
