Just stick a metal rod or something that won't bend in the cat, and knock the hell out of it with a hammer. Make sure you don't clog it up, either.
I clogged a cat up doing that on my 94 Thunderbird 4.6 V8, but when I kicked down on it, it blew the chunk out and opened up, lol.
But, anyways, you can gut them like that, or buy an 'Off Road Pipe' or 'Test Pipe', and it's just a straight pipe that bolts in place of the cat. Usually runs $40 +/-.

just did this on an 85 300. mine has two cats, one small one in front one large one
farther back, then a big muf. I cut the large cat from truck, then took apart the rest from the engine. then I used a rod with about 1 inch bend at end, bend it to 90 degrees, put other end in drill, insert into small cat from rear and start drilling stop
and shake out core repeat until empty. then go to local muffler shop with measurments for pipe that replaces large cat with straigt pipe I think mine was 27"of
2 1/2 id pipe necked down on one end to 2 1/4 od on other end clamp or weld inplace
reinstall to engine doing this way instead of just cutting all of it out, it still looks like you have a cat sounds better to. hope this helps plugged up cat will blow out gaskets,verrry frusterating good luck
ps why do starters always go bad in a snowstorm

If you're patient you can cut it off. That's what I did, I cut it right in front of the cat, but the crossmember was kind of in the way so it was a pain to get the sawzall in there, but if you're patient, you'll get it. Then just clamp on a 3" pipe to it straight to the axle, it's loud, but you're check engine light will come on. Mine did, but when I put on a muffler it went off, and now it only comes on occasionally. I'm still running only one cat though. Try it, it don't sound super good, but it's pretty loud...
