exhausts

    I'm looking to replace my stock exhaust on my Si. I was wondering what you all recommended. I don't want anything too loud but I want my car to be a head turner. So far I am looking at the Greddy Supreme SP, the K tuned exhaust, Full race exhaust, and the Skunk2. What do you all think?

    This is a brand new axle-back system developed by Injen. It will add a little bit of power, and a good amount of sound. Definitely much better than the factory exhaust! Honda Civic Injen Stainless Steel Exhaust System

    im already planning for my mods to the car even before i get it. but since im probably going to be putting nitrous on it im thinking of changing the headers at the same time. is it worth that extra money to get some nice 4-2-1 headers?
