Yeah you can remove the "aft" sensors with a tune. in IL they don't hook you up to the tubes (sniff test) or even look under your car.. unless you fail the ODBII...

So your looking for bolt in "off road" cat deletes for a LS2.... Did I read that right?

Oh yeah. I ran O2 spoofers on my GTP... I agree they work like a champ! cheap, and then you don't "have" to get a tune... although it wouldn't be a horrible idea anyways since your freeing up the backpressure on the motor by taking the cats out...
