Ed- could you talk a little more on what you did w/ the cat? I didnt quite follow...Did you pop more O2 sensors? Is there a plug in to prevent that? If Im following you so far that jeep had: cold-air/upgraded throttle body/high flo-cat(hole?)/1/2 size pipe restricter...? Did you have to re-gear that also or did you not have larger tires on it?
