A pliable refractory metal carrier (46) may have coated thereon an anchor layer (47) to improve adherence to the carrier (46) of a catalytic coating (48). The conformable catalyst member (26, 82, 82′, 126, 226, 326) may be bent to conform to a curved or bent exhaust pipe (20, 220, 320) within which

A pliable refractory metal carrier (46) may have coated thereon an anchor layer (47) to improve adherence to the carrier (46) of a catalytic coating (48). The conformable catalyst member (26, 82, 82′, 126, 226, 326) may be bent to conform to a curved or bent exhaust pipe (20, 220, 320) within which it is mounted. The pliable metal carrier may be in the form of a tube such as carrier (46) having perforations (54) formed therein, or it may be a metal strip (76) which is folded into accordion pleats (80) and has perforations (78) formed therein. The perforations (54, 78) serve to permit the passage of exhaust gas therethrough. A series of interior closures (58) and annular baffles (60) may be provided to import a serpentine flow path to gases flowed through an exhaust pipe (22) containing a conformable catalyst member (226) therein. A mounting member (68) may be supplied to fasten one end of the conformable catalyst member (226) to the discharge end of an exhaust pipe (220).

What is claimed is: 1. A conformable catalyst member comprising a refractory metal pliable carrier comprising a tube of corrugated construction, the tube having an elongate body portion which is dimensioned and configured to be mounted in a curved or bent configuration along its length within a bent or curved portion of an exhaust pipe having an open discharge end, the pliable carrier having coated thereon an intermetallic anchor layer having a catalytic coating applied thereto which remains intact on the carrier when the conformable catalyst member is bent along its length and mounted within a bent or curved portion of an exhaust pipe.
