when they scan the barcode thats on your door jamb, it has all of the car specs. like na or turbo, size of engine, how many cylrs, also all they have to do is look on the engine plate under your hood, plus i doubt your turbo setup is gonna look entirely stock, unless its SR20, which can look stock, just not for a USDM 240sx, esspecially when there are so many 240s out there owned by normal ppl with ka's they would notice a diference. sorry to burst your bubble

actually the barcode on the door only inputs the VIN number and no other info. The underhood label is what says all the specs. The smog tech determines required emission control equipment by reading the label.

edit: if you care dont buy a high flow cat. just get a normal universal one and take it out once you pass. High flow cats have caused many problems with cars that i've smogged personally. It works sometimes and not sometimes. I'm sure there are people on this forum who will tell you confusing stories about high-flow cats.
