So I'm interested in why this header would gain "more power than any other EL header out there" when it is basically a copy of what is already available. Both this design and the Perrin redesign have copied the Killer Bee primaries and have a less efficient collector. I don't buy that this will make more power. Since no one does true independent, back-to-back testing with the exact same car on the same dyno on the same day with the same tuner with competing products, I guess you're free to claim what you like, but by looking at the product it obviously doesn't offer any magical advantages.
