Default Replace the Cats?

So this could be a stupid question, but I had an idea. If I had an exhaust shop replace the mid pipes that had the stock cats with straight pipes, would I see a hp/mpg gain?

Also, I know that when you get LT that there is CEL problems, if you had the stock 02 sensors installed in this new straight pipe, just as they would be set up in the stock pipe, would you still have problems?

Finally, would removing your cats cause any kinda problem as far as making the motor run too rich or lean?
