Default 1997 subaru legacy BD JDM dual turbo automatic

Hello, I am a new member and I have been searching the FAQ and looking around for a few parts for my dual turbo automatic legacy.

I recently replaced the vehicle's exhaust system, replaced the two wire catback o2 sensor with a three wire sensor. large amounts of black smoke are now coming from the tailpipe.

I think maybe the heated 3 wire sensor is throwing the computer off since it may be waiting for the nonheated values to be registered in order to do its fuel management thing. so I am planning to return the two wire sensor If I can find one. t

* Can someone please point me to a two-wire O2 sensor and a source for parts for a JDM Subaru legacy Thanks for any help.
