The best bang for the buck modification is an intake, it'll make more power for you than an exhaust, and it's 1/3 the price.Check out honda-tech.com and clubcivic.com.
I have an '05 Civic EX, but I'm not modding it, just a stereo system. I have an all motor Integra GSR build, so I know a bit about modding.
Why would you upgrade the inahle without upgrading the exhale. Not a good way to make power correctly.
