Abstract

An exhaust system component comprises a housing including an inner surface having a first longitudinal axis, a core positioned within the housing and including an outer surface circumferentially extending about a second longitudinal axis offset from the first axis, and a mat positioned within the housing and compressed between the core and the housing. The mat is wrapped about an outer surface of the core more than one revolution such that a first circumferentially extending zone exists where the mat is x layers thick and a second circumferentially extending zone exists where the mat is x+1 layers thick. The second longitudinal axis is offset from the first longitudinal axis in a direction toward the first circumferentially extending zone.
