Zusammenfassung:	A METAL CATALYST CARRIER BODY (20; 60; 60A) INCLUDES LAYERS OF FIRST AND SECOND METAL SHEETS (40, 42; 82, 84) DEFINING PASSAGES (36; 74, 76, 78, 80) THROUGH WHICH EXHAUST GASES FLOW. THE FIRST METAL SHEET (40) IS CORRUGATED AND ENGAGED WITH SECOND METAL SHEET (42) IN EACH OF UPSTREAM AND DOWNSTREAM REGIONS (30 AND 32) AT NUMERAL CONTACT POINTS. IN INTERMEDIATE REGION (34) BETWEEN THE UPSTREAM AND DOWNSTREAM REGIONS (30 AND 32), THE FIRST METAL SHEET (40) IS OUT OF ENGAGEMENT WITH THE SECOND METAL SHEET (42). (FIGURE 4)
