Do any of you have one? What was your Horsepower increase? Is it comparable to the DC Sports header? Headers for imports are very expensive. I couldnt believe some of the prices for just one header. I called Jackson Racing a little bit ago about the header they have coming out. The dude told me the list price was like 649!! WTF? Header(s) *plural* for my mustang were only 150 bucks! Man. This import thing is getting expensive.
