[QUOTE="2012 Boss 302, post: 16024033, member: 137895"] I have no cats and an AED tune. I pass the OBD test no problem. A good tuner can work around the cats and rear o2 sensors IMHO the extra $$ spent on aftermarket cats is a waste. I am a mechanic and have installed "green cats" or "high flow cats". I feel like they are cats in name only. In order to be high flow the cell count must be lower, consequently they don't clean as well and will set a P0420/430 code..... [/QUOTE]
