Well I added up the parts needed, and this is the manifest to complete silicone FMIC piping for reversed manifold
type qty cost
90 = 7 = $118.93
45 = 4 = $67.88
straight = 1 = $49.99
joiner = 12 = $95.88
Didn't bother to figure in the clamps.. it's already too much.. and that's with out shipping.
I think I might just piece it together myself, and do like imma_stocker says and just buy aluminum piping and have it mandrel bent to my spec, then have it welded instead of silicone coupled together.
