Just passed smog in June with my Sho Y as well. Neither Toadster or myself were running gutted pre-cats or Headers though. 
And i think that the Pre-cats do most of the work and the underbody cat is just the added insurance. so if you run headers or gutted pre-cats you might pass on the high side. key word is MIGHT. are you willing to take the risk?
you could probably take the precats off and put your headers and when its time for smog, put your precats back on. its up to you if you wanna go through the hastle every 2 years.
I have MIL eliminators for sale. home made using surface mount components so the pcb is smaller than a nickel. i can shoot pics for you. shoot me PM if you'd like them.
ohh and i just bought new pre-cats and i really didnt feel the difference between gutted cats or new pre-cats.
