The only problem I can see with this is that they are cheating the radius on the manifold. Meaning that the pipes are on an angle right off the flange. This in thoery causes problems with flow and also creates a hotspot where the exhaust shoots out of the head and hits that corner instead of coming out straight naturally then going into a bend normally. If this is going to crack it will be in 1 of 2 places. (I makes SS manifolds so I'm going on experience here). It will be right where the tubing is attached to the flange because of that instant angle, or at the collector because of the weight of the turbo hanging off the manifold. Generally it's not heat but just the sheer weight of the turbo that causes the manifold to break eventually.

Now with that in mind i'm only going off looking at 1 picture so it's hard to tell if that is acctually the case or not. It' looks like nice material and some thought went into the construction. Really the best way is to find some guys who have them and see how they go. I know OBX-R makes a turbo manifold for a lot of different cars and they crack in about 2 months because they are crappy construction.

This company re-packs and sells OBX-R manifolds as their own. They looks nice but end up in the garbage pretty quickly, hense the $195 price tag. They are made in Taiwan very cheaply and from poor quality materials.

adfx makes really nice stuff but you will end up waiting forever for it. if you can just use what you have now while your waiting, i say go for it.
