Well, if a person were to do such a thing, (I have no idea who that would
be), they would take the cat off and use a bar or pipe and smash the ceramic
core into pieces small enough to come out. Sounds like yours is already
broken loose, so you wont have far to go. But, then you have to disable the
rear O2 sensor or you will get a trouble code. Companys make "Cat boxes"
that simulate rear O2 signals (for off road use only, of course), but I cant
think of the names right now. Anyone??

air flow without removing the cat from the exhaust line so i can pass the
visual inspection here in PA (We don't have emissions testing in my county)
