Do you have emissions tests? Do they check for cats? If not, I'd probably remove them.
If you do, the choice is really up to you, but leaving it alone is not really a good option. A clogged cat will kill your power. My mom had a bad cat on her Monte Carlo, and it felt like it couldn't leave 1st gear. She had hers replaced under warranty - cats have a longer warranty than the rest of the car. You may want to check with your local dealer to see if yours is under warranty.
I'm very happy running without cats. I don't have any rasp, and only have a mild gas smell - which is how it should be anyway. Because of my experience, if you need to only pass a visual inspection, I'd go hollow.
BTW, I won't vote until you give more info about any inspections in your state, but at least you have my reasoning.

If you can get away with not havin em where you live get em out of there. I could get by without them here as they just plug the OBDII in, but in the case they decided to look for inspection or being loud.... I decided to go for the high flows. Just so somethings there.

Damn it. I meant to click on "high flow cats" and I instead clicked on "hollow cats" 
Take one away from hollow cats and add one for high flow cats. Magnaflow 5995's are the only way to go. I can't wait until mine come in the mail.

just the other day i was with my friend going to a muffler shop in his ta and it started whistling from the exhuast. he gunned it and all the cat **** started flying out the back, so when we got to the exhuast shop the dude gutted it and put a flowmaster 80 series on it (the forums preferred choice lol) and now it sounds badass and you can tell it was chokin the exhuast hardcore before it was fixed. btw it was a 94 lt1 if that matters to anyone

I went with metal matrix cats for my true duals. I love em, still loud and actually feels a lil faster, These motors like back pressure, and it felt like i gained with them from when i didn't. Their expensive but compact, and flow very well.

No cats. If your ride is low. No one is gonna get on their knees and look. On the trunk, I have to have them on cause you can see everything underneath. Probably wouldn't pass. So anyways delete the cats, SIMS, or delete codes out with tune.

Guys with LT's and cats..... Do any of you have pics of where they are mounted? I am going to have mine welded on in about a week and the exhaust shop by me said it can't be done (driver's side). I just wanted to take a pic to him so he would have a rough guide.
