under the graphs they have pictures and that's what i was understanding from them. yes from the discription itself it pretty much said the shorter the better but then in the pictures it says this "The inside of the manifold is split up. The 1st and 4th tubes come in junction with the 2nd and 3rd tubes to make up a 4-2-1 design. The gases are designed to cross in a pattern of cylinder 1, 3, 4, and 2 into the turbine, according to the ignition."
Which i believe relieves some of the side to side pulses by keeping the air flowing by the cylinder relief pressures not interacting with eachother but working together. I could be wrong but that's what i think.
