ok so im wondering if its legal to put a cold air intake on a car in VA, i dont live up north i dont have any emissions or anything

i ordered a PRM intake for my s2000 an i have watched videos on you tube an such an its loud (specially when V-Tak kicks in yo)

the reason i ask this is cause i plan on gettin a exhaust that looks pretty stock an was thinkin if i get pulled over for sound i can say the exhaust is stock but i added a CAI that makes the car alot louder....... granted i wouldnt want to say that if the intake is illegal....... so any one know about the legality of a CAI
