haha wow whoever told you that is a re-tard. if that was the case I dont think nascar would use straight pipes.. but in my experience as long as you have a one cat and a O2 sensor before and after the cat you should be fine. I have high flow cats on my truck and i dont throw codes or anything and still pass the 49 state emission test( california is the only state that i dont pass in but i am excempt since I am military) and if you do gut the one cat before the downstream O2 sensor it will throw a code telling you that this "O2 sensor High Voltage" and spit out a number for the O2 sensor bank 1 or 2. and that will make the computer to adjust the fuel for the rich fuel mixture and the computer will adjsut the injectors to back off the fuel until it can't adjust anymore and then it will set off the CEL
