Well I decided to check one out personally and worse come to worse use it for flanges. It was better than I though.



All 3 of the flanges where "decked" for warping and I checked it with a straight edge, no warping at all on any of the flanges. All of the wields have "reinforced" on the inside, (only complaint) is they are not that pretty, it was mig welded inside, some of them where cleaned up though. I had a good friend of mine look it over, other than ugly welds he saw no reason to redo them.



The steel was little bit over .100 thick.



Only real down side, after a quick inspection, is the wastegate port opening, I couldn't find my dial calibers to measure it, but with a tape measure it looked to be around 38-40mm. Preaty much defeating having 46mm TiAL for it.



I couldn't check the engine fitment too well, I just noticed that I am missing 3 exhaust studs, by eye it looks that will not be any problems.



I will try to take some pics of it, before I drop it off at the cyro place (which I do to all of my manifolds to prevent cracking), if anyone is interested in it.



I don't know how well it last, but it should hold me over till my friend can find time to build my manifold.





After its cryo treated it have a thermal coating applied to it.



After reading most of the posts SSAutochrome, I was expecting something much worse, it looks like SSAutochrome reworked it a bit, but, to me its worth 170 with shipping I paid for it.

Good luck. Hope it turns out well for you. You are a braver person than I am to be willing to take on the guinea pig role.

i bought one for $99, it must be an earlier one, the flanges were decked AFTER they drilled and tapped the holes, so the studs are all at weird angles.

Steel or stainless steel?

MIG SS welds...oh boy...

Looks to have used stainless wire.
