dyno runs are not where a cai was born to be ..

and you are not just looking at peak power ..
i raced a dc5r .. first time it was stock .. i beat it by 1 car length ..
second time .. it had aem cai and cat back exhaust ( no hfc)
beat me by one car length..

dun tell me it does nothing mate ..
just use common sense can u can think about how it will be better..

anyway .. if u wanna get a cai.. do it right first time
pay the $$ get a decent one ..

no one would buy it if it costed that much and did jack shit ..
do u think people are stupid ?
