Ive heard different stories, I think it goes by which shop you go to. My closest shop wouldnt let my gf pass with a check engine light. Automatic fail.
I just today got my emissions testing papers... I have 2 months to get it done. I am catless, I will go soon and see if I pass (I heard they dont use the sniffer). If I pass Ill let everyone know. If not, I have my stock exhaust in the garage. My Accessport shuts off the CEL so it wont register if they pop in the OBDII port (Which im 99% sure they do)
