hey guys, im pretty noob when it come to performance upgrades hence the reason why i havn't done any done to my allex! i want to give it a little bit of power, and i heard installing a CAI or a new exhaust system is the most basic of performance upgrades. now i'm confused on whether to install a CAI first or an exhaust system coz ive heard a few things 1) if you install CAI you will need to install exhaust system anyways 2) CAI wont allow you to notice any difference so no point having it alone if i could just get some straight answers and opinions that'll be great! Cheers
