Abstract: A mixer comprises a first subassembly including a first holder fixed to a first mixing element. The first holder includes a base interconnecting a first sidewall with a spaced apart second sidewall. The first mixing element includes a base interconnecting first and second spaced apart mounting flanges that are fixed to the first and second sidewalls. A second subassembly includes a second holder fixed to a second mixing element. The second holder includes a base interconnecting a third sidewall with a spaced apart fourth sidewall. The second mixing element including a base interconnecting third and fourth spaced apart mounting flanges that are fixed to the third and fourth sidewalls. Distal ends of the first sidewall and the third sidewall are fixed to one another. Distal ends of the second sidewall and the fourth sidewall are fixed to one another.

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.
