alright i just got an 08 si and need to know something to do performance wise to get more power that is affordable im already getting a cai now i need another affordable option to give my engine more power

 

Headers.

 

I would look into a hytech or DTR/SSR header, high flow cat and a quality cat back exhaust. then if you have any money left get some IPS cams

If you want to learn alot about K series engines and what parts to make power with you got to check out http://www.k20a.org/forum/index.php

 

it's "header". there's only one since it's an inline engine.
