I have only had my fiji blue 06 civic si for about 6 months and am just now starting to do upgrades. I am about to do the CAI and Cat Back and was wondering what everyone suggested? I have been looking at the injen exhaust and CAI. What does everyone else think???

 

not to be a ***** but if you look down the pages there is a thread that is titled what was your first mod..you will find your answer there

 

Also, read the rules because you are in violation.
