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.

An exhaust system component comprising:
- 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 outer surface of the core and the inner surface of the housing, the mat being wrapped about the 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, wherein the second longitudinal axis is offset from the first longitudinal axis in a direction toward the first circumferentially extending zone and x is an integer having a magnitude of at least 2.
An exhaust system component for a vehicle having a target region at which a feature of the exhaust system component is to be oriented, the exhaust system component comprising:
- a housing including an inner surface;
- a core positioned within the housing and including an outer surface spaced apart from the inner surface of the housing;
- and
- a mat positioned within the housing and compressed between the outer surface of the core and the inner surface of the housing, the mat being wrapped about the 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 circumferentially extending zone being separate from the first circumferentially extending zone, wherein a gap between the outer surface of the core and the inner surface of the housing varies in radial size based on circumferential position, wherein the radial size of the gap provides the feature to be oriented and x is an integer having a magnitude of at least 2.
