Probably an oxygen sensor (behind the cat). Because you're running HFC's.

It's working.... it's just that it throws a code because its range has been exceeded. There are a few fixes. The best would be to have an UpRev tune and eliminate those 2 rear sensor inputs. The problem will be permanantly solved. You can also extend and protect the sensors with bungs and steel wool (this is not a permanant fix).

It won't be the cat itself that's bad.
