Planning to keep this car for a while as it is a fun car to have. I am not going to go crazy on this car like my previous ones to the point that it is not smogable and have to sell it. Question is in CA what mod is straight up fail on smog check Would Pulley Tune Meth kit Nos Exhaust with muffler and header with cat be OK? Or a modified exhaust be a easy fail? What is the smog law on "modified" exhaust ? Be OK? If they plug in the obd, would they be able to tell u have a tune and fail u? I am leaning toward lower pulley and tune... What do u guy think?
