anyone built a mani for their 12 cm ts holset?

[Cdc1221]

I want to build my own divided t3 Mani for my hx35, but I don't want to order too many or too few bends. If anyone has built their own, would you be kind enough to give me a shopping list? Which tubing would be best to use? Thanks in advance

1 1/4" sch 40 mild steel or 1 1/4" sch 10 stainless steel
6ft of straight pipe
4 90 degree bends per cylinder
(king architectual, ace stainless, or local pipe fitters)

Cylinder head flange (ebay)
Turbo flange (ebay)

1 1/4" is plenty big enough and is a good size to learn with. Gives you a lot of space and will still flow well. 4 bends per cylinder gives you the opportunity to make a mistake or two without it becoming totally FUBAR.

If you think about the collector, you need at least 4" to make each piece, even if you make them perfectly you need somewhere to clamp to in order to cut it. If you make 4 4" long collector pieces perfectly you've already used up 16" of straight pipe. One mistake or a 6" long collector piece you won't have any for the manifold. You may consider getting a stick of the stuff, I get mine at the remnant yard for cheap, so I have random sizes piled up in my garage.
