Will my honda civic fail inspection if i add some aftermarket parts?

by parts i mean if i take out the stock air intake system and put in an aftermarket cold air intake. also if i replace the stock exhaust with an exhaust system(catback). and would it matter if the car has a low body kit or not?(i cant see why a body kit would be a problem) its a 1997 honda civic DX coupe .Will my honda civic fail inspection if i add some aftermarket parts?As far as intake and exhaust, they pretty much are all legal. Make sure whatever you get has a CA smog number. Even if you dont live in CA, if its CA compliant you won have any trouble passing smog because CA has the highest smog restrictions.Will my honda civic fail inspection if i add some aftermarket parts?Actually the body kit can cause the most problems I don't know about were you are but in PA, it can only be a bolt on the stock dimensions of the vehicle have to be the same or it is not legally inspect able. Meaning you have to leave the original bumper under the aftermarket. I don't know about the performance mods. thoe.
