I had one on my 00. Your emissions test is just an OBDII scan. As long as your SES light is not triggered (which mine was not), you will have no issues. Dealer also didnt give me any probs.tbh1984 said:Does anyone have a y-pipe on their Maxima? If you do, have you ever not passed emissions? I guess my main question is...do any of the dealerships give you crap for having a y-pipe?
