I did read it and started looking for what u said before i could answer you,
So your saying that if i use 2.5mm pipes i should make fewer jets (cause i already bought the pipes and really cant go and buy another size, too much trouble here where im living). Lets say 19 or 21 jets, do you think it d make any difference, and it would be too restrictive?
edit/ Dont take into consideration the number of holes in the pics. They are just for u to have an idea
