> If your going to mod a new Civic SI be prepared to run an Engine Management system like K-pro to optimize your bolt on’s. I’ve seen great gains when doing just an intake/header/exhaust and then tuned with K-pro to set it off and get the most out of them.

In reguards to an exhaust, spend the big money on the header and get a K-Teller exhaust made up for you then have it installed. Run a minimum of 2.5 inch with the K20 if you plan to make good power. For the intake, take your pick. Just dont go Egay style and kill your motor.

thanks for the tips. i already have an aem cold air intake, which has worked well as far as i know. for what its worth, im not a noob when it comes to modding, i have built a dsm motor under the watchful eye and instruction of carnut… but i am not familiar with quality honda aftermarket brands.
