Gerard, I'm not sure what youve been smokin down there but I suggest you
let up on it a bit. These questions have all been discussed at length
many times, and re-re-re-answering them for the same people is getting a bit
old. For the last time.
10V - NA get the 5>3>1 manifold for best power
10V - T get the two piece for best power
20V - NA keep the stock piece
20V - T get the RS2 for best power
