i kept my stock when i put the cai on it. cuz one of my friends took his truck in and thay woudent inspect it because it dident have the sticker... what you should do is, if you have a friend like with a AEM.. of injin. ones that have carb stickers.. just barrow it off thers and put it on yours till u get it inspected..
kida ghetto but it should work.. good luck bro..
