MY 2005 SUBARU LEGACY i HAD FEW CODES P0420, P0137 AND P2096 ON BANK 1. I REPLACED THE O2 SENSOR AND REPLACED THE CATALYTIC CONVERTER. BUT THE P0420 CODE STILL THERE BUT DOES NOT SAY ON WHICH CAT. I WOULD LIKE HELP ON HOW FIND OUT WHICH ONE COULD BE?

I HAVE A 05 LEGACY i and I have a code P0420 code for Catalytic Converter Below Threshold Bank 1 and a P0137 02 Sensor Low voltage Bank 1 sensor 2. I've been looking for a new Cat to replace mine but the OEM is too expensive and most of the Cat that I find online cannot be shipped to New York. Does anybody knows which Catalytic should I buy? any recommendation?
