Hey you're in Little Rock! So am I. Sorry to hear someone cut your cats off. That's completely ridiculous.
You could put a pipe in place of the cats temporarily, but it will be a whole lot louder with the air restriction from the cat no longer there. You'll also probably lose some torque. It probably won't damage your O2 sensors, but will throw a code. I'd get it replaced asap. I'd take it to Marty's Muffler out in Jacksonville. Great guy, great service, great price, and he will custom make your exhaust the way you want it and let you watch. Good luck.
