Default catalytic converter

hi there
i removed the exhaust line and cats, got a release bearing
failure. with the cats removed im thinking too gut them,
i live in quebec so no emission test. i know it will not give me 50hp.
but i would like too have somes info about the cons etc.
its a 96 lt4 with odb2.i seen on net guys used 2 spark plug anti foulers for o2 sensor after the cats.
i heard on net about back pressure etc.
please tell me if its good from your experience and how too do it please.

There is no reason to remove them on a street car, removal or gutting will make no diff. except make it a bit louder. No performance enhancement.

I used the 2 spark plug anti fouler trick on my Dads 2004 Mustang GT when we put a catless mid pipe on his car. To my surprise it actually worked. He drove that car every day for two years before he traded it and the check engine light never came on.
