If u want a cai, then you are gonna have to remove the resinator. Removing the resinator is easy, the only thing u need to do to make removing it easier is just to jack up the front of the car a little bit so you can get to the bolts easier. Its either that of to remove you whole front bumper all together. My .02 If you live in an area that has a lot of rain, Getting and AEM bypass vavle isn't a bad idea either. Then again, avoiding big puddles would be a good idea too :naughty:
