OK I have been looking into getting LT's with and ORY does the ORY take out the cats and if so do I need O2 simms or what is the best course of action.

Noob in trouble.

No it doesnt take out the cats unless you make it, if you do elmintate your cats, your check engine light will be on until you tune out the o2s

Why don't you do away with that Ole "Y" pipe and go with over the axle true duals that exit out the back in the stock location?

The Off road y-pipe does not come with cats. All you will need is so o2 extension for the front o2's and o2 simulators for the back o2's and witht this your can will not throw any check engine lights. But with long tbue headers and ory you will wount to get a tune anyway so don;t worry about the o2 sims just tie they old ones up out of the way.
