CONVERTER WITH INCREASED FRICTION

摘要

An outer shell of an exhaust component includes an external surface and an internal surface defining an inner cavity. At least a portion of the internal surface has a non-smooth finish, such as a textured surface for example. A substrate assembly is received within the inner cavity and is in contact with the portion of the internal surface that has the textured surface. The contact between the textured surface and an outer surface of the substrate assembly prevents relative movement between the substrate assembly and the outer shell.
