I have an 88 5.0 five speed with shirty headers and a flow master h pipe exhaust with cats. I do not like the flow master muffler sound and want some suggestions for new mufflers to get

If you don't like the chambered muffler sound, you should look for a straight-through glass packed muffler. MagnaFlow is a good suggestion. I happen to have a pair of them on my car now, but I'm still a sucker for a set of flowmasters on a fox.

If I hollow out my cats will that f with my o2 sensors or will it still run right?

Instead of destroying the cats (that you may want to put back on), buy an offroad x or h pipe. Do it before you mess with the mufflers, losing the cats changes the sound drastically.

I went from cat-less bbk to having "high flow" cats welded in(state inspection, car came w of road bbk x) and it was noticeably quieter. However, it was nice not fumigating my date w exhaust fumes.
 
BBK lt's, BBK catless h-pipe, Super 44's to tailpipes out the back gives me my jollies when I drive my stang. I like her loud and proud and oh yeah....

I still think flows are the best sounding muffler for our car. My current setup is bbk shorties off road h and 40 series. It is load as hell but I love it. I also ran the same setup with a dynomax catted h pipe which was a little quieter and helped with the drone. I really liked that h pipe and would reccomend that with the magnaflow mufflers as well

Your setup is almost identical to mine but I have flowmaster 40 series. Haven't heard it yet since my motor is on a stand right now but I'm excited and hope it's loud, deep and throaty.

Just going to an x-pipe from an h-pipe would make an exhaust sound more raspy, add on top of that a glass pack type muffler and you will only get more raspy. X pipes allegedly flow better at higher rpms too
