Interesting...why two different design if you're going to couple the same cylinders? maybe it's hard to tell from the pictures but they are two different diameters? The one on the bottom seems slighly bigger.
I'd guess you'd need a manifold for NA cars and a different one for FI cars.
I'd go for a bigger stepped 4-into-1 manifold for track car, both NA and FI, to maximise the top end power above 4000 rpm.
They don't seem to be much different from the stock manifold, exept for the absence of the 1st cat.
What's written in the sign?
