Of course it will pass, it's downstream of the cats. The only thing you have to worry about is the visual inspection. You should be able to get away with smog if your state goes by Federal standards. So basically anything downstream of the cats they could care less about. If not, you could take off the turbo put your lid back on in a few hours.

I believe most people run cats. One person on here said they only gained 8hp from gutting their cats. Definitely not worth it.

If your old LT1 cats are junk then it would be worth it to get a couple performance cats. If they still look nice and clean then keep 'em.
