I'm not sure if it would still pass emissions with just two stick cats.
You'll be shutting the rear O2 sensors off if you have a tuner. If you don't, you'll need two MIL eliminators. In either case, you should probably make sure the sensors aren't moved so you can leave them plugged in. The emissions tech may look under your car, so you want it to look correct.
Try to get them to keep the mid pipe dimensions correct, that way, you could replace it down the road if needed without having to mess with the rest of the exhaust. Also, this will make it easier if you decide to get a cat back setup in the future too.
