I have no mufflers and would like to remove my cats also. Would I just replace them with a piece of pipe and put the O2 snesors in that pipe?

LOL!
To the poster: Unless you've got a 13.5:1 race motor that we don't know about, running with no cats AND no mufflers is NOT a good idea...you'll loose power throughout the RPM band.
Now, ditching the cats and running some nice aftermarket mufflers will give a noticeable power increase AND a nice new rumble.

I like the rumble its got now. I was just curious, but I knew it would kill my backpressure.Swarzkopf said:

You like the rumble it has now because it has cats...quite honestly, a stock compression, stock valvetrain 5.0 sounds like absolute ass with no mufflers and no cats...all raspy with no real "tone" to it. Think of a 1985 Caprice Classic with rusty muffler...
And it's not "backpressure" you want per se, it's scavenging, which you'll hurt dramatically if you ditch those cats and run no mufflers.

I hate to fart on someone's idea, but personally I also dont like no muffling of any sort (cats are decent mufflers). I've run cars with just cats (no catback - dumped at the cats.) and it sounded decent IMHO. It sounds like you would not have an means of joining the two exhaust pipes (X,H, etc) and that might hurt the sound too. That said, exhaust is SO highly personalized, no one can say (and please take no offense at my comments - it's just my perspective. When in HS, I thought glasspacks and cherry bombs and nothing else were great. As I got older, I got to liking more subdued exhaust). That said, I love my Mac shorties, catted H and catback (it's friggin loud).
Do you have a bud with an O/R pipe? I would swap it into your car for a test drive - see how you like it. If you do, buy one. If not, now you know and saved some cash.
Though you might want something more glamorous, I picked up a Summit H for the fox and it looks like a decent piece for 100 bucks.

No muffling of any sort sounds pretty damn good on solid lifter, high compression, 700hp race motors...
It just doesn't work on stock 5.0s though.

I would just get a cheap o/r H and fab some piping into some cheap magnaflows, and leave the mufflers open. No pipes going out from the mufflers, or some turn downs after the mufflers.
I think you can pick some magnaflows up from a muffler ship for under 50 a piece, and the piping should be somewhat easy to fab. You could even use your stock piping.
Just make sure you get the right size inlet and outlet diameter on the muffler for the piping you will run.
That would sound awesome, so loud...annoy people for miles, but it won't sound like ass, like it would w/o mufflers/cats.

I beg to differ.

Well I like it. And its not loud unless I get on it.
I have 2 Hooker hight flow mufflers in my shed and all the stock exhaust, but i love my side pipes.
