The mil eliminators splice in between the wiring harness, and your o2 sensors. Or, you could pay 60 bucks for the plug in ones, but they all do the same thing. You can get the splice in mil elims for 8 dollars shipped off ebay, and if you can add 2+3 you can splice them in. If you gut your cats without them it should enter limp home mode, and your beast will not be so much of a runner anymore, and gas mileage will drop significantly. I don't know about mpg differences in relation to gutting cats. I'm sure there are just as many advantages as disadvantages when it comes to taking the cats off. Some will argue about loss of backpressure equating with loss of torque, but I'm pretty shure it just shifts it to a different point in the rpm band. Hope this answers your ?'s.
