Well, i'd prefer to have bought one, considering i had to buy a welder and a bunch of consumables, a horizontal bandsaw and an expensive premium blade, carbides to grind with, piss around with spare flanges getting it right (and destroying those flanges in the process), buying way too much stainless so that i didn't run out (and ruining half of it). I had also bought an expensive carbide tipped chop saw blade - and found out after 2 or 3 cuts that they don't last very long. So honestly, this wasn't exactly fun. But now that i know how to do it and have all the tools i could reproduce it more reasonably than the total cost I have spent this far. Its based more on these: South Florida Turbo manifold inline pro manifold lovefab lovefab DCR Guys have run 9's and 10's on all of those manifolds above. The goal was to have a full size high angle merge collector and the shortest runners possible for spool up. I also wanted to avoid unnecessary "up then down" bends which are bad for flow. I rotated the angle on the merge collect and made all the paths as smooth as possible while still maintaining a high angle merge collector. I considered/mocked up manifolds such as this: But decided that the direction I went in would flow better due to the proper merge collection, and no "up then down" bends. I chose good merge collection at a high angle to the turbo and shorter overall length, over a more equal length runner.
