Emissions
I finally installed a set of lt's on my 93 Vette, along with a b&B exhaust. Problem is now i have no 02 sensors and no pre cats and the rear cat has been pounded out so what do i do for emissions? is it going to pass......

no O2's? WTF? assuming your serious.... hell no it wont pass emissions. Removing changing or modifying Catalytic converters, EVAP, AIR, EGR, O2's, even certain unapproved headers in almost anyway will fail you on a visual inspection.
Now, if your only talking about the sniffer part, I'm not sure how the vettes exhaust is run (are there two sets of cats? if so, why?) but, camaros with the LT4/LT1 only had one set of cats and you usually will not pass if you remove them.
Then there's the codes for not having O2's... you'll need sims or to tune them out. SES light for emissions equipment will fail you.
