The gains are there, however minimal. Proof that they do indeed flow better than stock.

As for the Mugen, it simply isn't designed to make power with mere bolt ons, much less a stock setup. It's designed for a high compression, aggressive camshaft setup. The same is true of the Spoon, Toda, etc. They will show a drop in performance up until about 6500 RPM. This may sound high, but keep in mind that they're designed to work for seriously built all motor setups, where a 9500+ RPM redline is fairly common. I'd like to see the dyno in that case of the stock manifold (or the DC, RS*R, Airmass, etc) vs. the Mugen, Spoon, Toda, or even the JDM ITR header.

I wasn't snapping at you before- actually, I was agreeing with you- anybody with an intake and exhaust who says he can feel the difference after installing his header is delusional. However, with any serious setup, removing bottlenecks is key.

And I was just saying- I don't know dick about domestics.
