Claim:
A converter assembly comprising: an outer shell having an outer surface and an inner surface defining an internal cavity; at least one catalytic substrate received within said internal cavity; and a sensor boss support positioned within said internal cavity adjacent said at least one catalytic substrate, said sensor boss support comprising a solid inner ring with a single-piece body having an outer circumferential surface with a sensor boss extending radially outward from said outer circumferential surface, and with a retaining flange portion being formed at each edge of said solid inner ring to extend radially outward such that said retaining flange portions have a greater diameter than said outer circumferential surface, and wherein said sensor boss extends outwardly beyond said outer surface of said outer shell, wherein each of said retaining flange portions terminates at a radially outward surface that abuts against said inner surface of said outer shell, wherein said outer circumferential surface is spaced apart form said inner surface of said outer shell to form a gap; and a mat wrapped around said solid inner ring to at least partially fill said gap.
