Not sure if he is going to make it one or two pieces just yet. If it's two pieces, it will have slip joints, not flanges. If it's one piece, I will probably have to drop the forward cross member to install it, no big deal, really.
The Mugen primaries are twice as long as stock?? Does anyone have a picture showing the Mugen vs. stock header?
The header is made for some serious breathing capacity, so you might not seem much as far as gains are concerned if you haven't done quite a few mods. Keep in mind that the headers are designed with the engine modifications and goals in mind, so what might work well for me, might not work very good for you.
I will be sure to post pics. My rods are supposed to come in next week, so I am getting very anxious about getting my car back together!!!
I can't make any comparisons with the Spoon header. I never installed the Spoon, and I have already sold it.
