You see Kamikaze makes 4-1 headers and 4-2-1 headers, but to me I really can't see the difference their 4-2-1 would provide since it's not really 4-2-1. The manifold already goes into 1 so what would splitting back into 2 provide? More backpressure?

I know a few people on the board running Kamikaze's and the one with the best power (AllmotorLS) is running 4-1's. Usually 4-1's literally only go to 1 near the collector, but these do it way before, so I just don't understand what their dual pipe configuration would do! I'd like to hear some technical critcism on this! Thanks
