My only experience with catalytic converters was a 2002 Buick. At 8 years old and about 60K miles the cat fried and stranded my wife on the highway. Towed to a repair shop, quoted $1300 for replacement. Called several other shops, all wanted $1100-plus.
Local muffler and exhaust shop provided a generic replacement catalytic converter, installed in about an hour with both O-2 sensors replaced for about $375. Repaired vehicle provided another couple years for my wife, then went on to a grandson for several more good years of service.
Apparently there are replacement catalytic converters suitable for many applications (overall dimensions, intake & outlet, capacities, etc), and most commonly seen automobiles can be fitted without resorting to OEM spec parts. Of course, many shops choose to quote repairs only at maximum prices and profits.
