It should not be a problem. Because I had that set up for a while. Your headers will replace the stock headers and cats. You will most likely remove the stock Y pipe and use a 3 inch Y with or with out cats. If you still have your stock cat back it will connect right up to the Y pipe.

same here, but I would think twice about putting the cut-out in the I pipe. It won't do you much good to go from 3" Y to 2.5" I to 3" cutout. I'm gonna put my cutout in my Y pipe.

I like having the cutout further back, so I'd go to 3.5" I-pipe, move the cut-out closer to the axle and then use 2 reducers to neck down and go over the axle.
