I don't know but my advice is wait and do some other mods first. But if you don't want to don't spend more than 300 for anything. Greddy has 4-2-1 and people are saying that that is good for low end power. I don't know I'm kind of annoyed by my decision if I sound like a dick.
I am ready to buy a header. If you look at my mods list you'll see I got just about everything except internals and forced induction. I saw OBX header for like 225-250. They look quality and the guy I talked to on the phone swears they are high quality but the tag on it is a little low, from my experience, and says possible problems. I was just wondering if anyone has tried one out or konw someone who has. Which header did you go with?
