Step 1 done, only 41 left. Manifold Build
Just ordered parts from JGS to make my own exhaust manifold. I hope it turns out like it looks like in my head, lol. But it's taken several diffent variation already on paper... I guess once I get the weld-els and measure, the final design will reveal itself to me.

wow. i guess i didn't realize the heft of 1/2" thick steel. This flange will crack some skulls... Looks nice. hopefully I'll start mocking up/measuring this weekend.
Oh, as an added bonus, they threw in an extra piece of straight pipe. That was nice of them.

(reposting in the right thread..)
basic design.. Simple, effective, and somewhere between a log and full 4-1 design. The runners for cyl 2/3 will go straight out. Cutting the center elbows and welding them like the picture will help direct/smooth exhaust flow, and keep the pulses from 1/2 and 3/4 seperate. The turbo flange sticks out about 5.5", and should leave room enough for a 2.5"dp. I may end up rotating the center portion about ~30* up to help clear the 'shelf' area, but preliminary measurments says it should be ok as is.
-update-
Today I made the collector section. The weld-els are easy to weld, but it seems the flanges will need another pass, not as easy to penetrate. I didn't have my camera handy, so no pics today...
Oh, I also need a new welding helmet...

As for a welding helmet. I got an autodarkening one off ebay for like $38 shipped. It's some chinese black thing, but it works great and beats the heck out of paying $100 for miller/lincoln.
If you haven't started fabing up the manifold completely, have you seen the ETD shorty mani? It uses similar design to yours but is closer to a top mount. It looks like it would flow great without worrying about puting the turbo to close to the shelf.

Pics:
parts before
I still need to clean it up before I write it off as done; the weld els to flange isn't all the way around ( i had dinner plans so I had to stop where I did) This is my first time with flux core, and it's different from gas sheild, that's for sure. Just takes a little to get use to:

Braineack,
It's not street car. I don't have any recent pics other than this one last year. Picture it with a grey racing beat bumper. It currently sits on a trailer at my folk's house:

More fun today. Grinding straight pipe to fit on the compound curve of a tube, that's bent 90degrees, and rotated 45degrees is fun. Lot's of sparks. Very relaxing and lets the mind wonder about life, the universe, and everything 
And then tacked into place. No making fun of my quick and dirty tack welds, it was dinner time...
After consideration, I ended up tilting the collector section about 45* That left enough room to clear the brake cylinder, valve cover, and hood.
