I am looking at the next mod for my z, I have basically a stock z, with only a popcharger. I was looking for an opinion on the best all around mod. I have about 400 bucks to spend. I am not particular about an exterior, or engine mod. Anyone want to give me their ideas on the next mod for less than 400 bucks. I was looking at the intake or the headers but, im not to familar with these products. Anyone fill me in with their advise?
