Recently after a wash down, I realized that its time to actually do some work to the 04 GP. So my question now what are some decent mods that aren't going to put me in debt. I wanna know what I can get to put a little pep in the step, and how hard and what am I going to go through with putting a different exhaust on it? I know im gonna throw a cold air on it, but as engine that's as far is it goes that I know of for the newer style. exterior wise....well anything at the moment will help. I appreciate any ideas!
