I would leave the cats alone and just change the exhaust from the catalyst back. Back pressure has nothing to do with it. Removing the cats will gain very little HP and will cause issues with the rear O2 sensors resulting in a check engine light. Also removing the cats will void your warranty and it is illegal.
