I am not too familiar with this. There is something that Burger Tuning makes I think (I feel like I read that somewhere on this forum) which would essentially be a simulator. People have also used spacers to pull out the O2 sensor with different success rates. And finally one of the vendors here makes an O2 sensor that is surrounded by a cat (call it a mini cat or something like that) which is plug and play as well.
All that being said, if you are eliminating the primary cats, the best is to get a tune and extract the extra power and get the other benefits of the tune.
