4. PS, you might want to plum that Wastegate pipe back into the exhaust, cos mine is now and it is STILL LOUD! Dumping to atmosphere like that, unmuffled, is going to be crazy loud! 
1. He has the 2" primary original prototype headers (the big HP number ones  )
2. Thermo Tec 2000d paint. No worries IMO. (Also wrapped too IIRC)
3. He is running a T3/T4 hybrid. Much different and larger then the small T28's
4. Definitely agree there. While it doesn't get any better for wastegate control and stopping boost creep it is uncorking the exhaust when you do hit your boost limit. If you keep it that way I would look into running a small engine style muffler on it to help quiet it down. (Yes I had thoughts about that on my friend TT setup )

Demon, I think you are looking at the wrong end of the downpipe to me. In one pic it show the exhaust end (not the turbo end) of the downpipe with the flange pointing up. I worked it out - it conect the the downward point flange connected to the rest of his exhaust.... Carry on.

Carry on.
You score an A+ !
I thought that the angle worked best to make room for the flange behind the motor mount and accessing the bolts.
The down-pipe and its connection to the rest of the exhaust is my favorite part because I designed it based on factors I thought were important.
The paint is Thermotec 2000D and its great stuff! It also makes it look pretty. All that stuff is header wrapped now as well so there wont be any heat problems. I might have some piping rot out in a few years but the sad part is I'll probably not be driving it as much now. I decided that I'd get it running then replace pieces of pipe with stainless as necessary. At least the primaries are stainless already.
The back header is done now and painted up also. Its a better design than the front one is. I didn't have it ready when I took the pictures.

Oh yeah, the vent to atmosphere. I really wanted to plumb it back in at first, but I figured that I didn't want it going back in right next to the turbo for turbulence and power reasons. I also didn't want to make a separate exhaust system for it like the Corky Bell book recommends, so I decided I'd vent it to atmosphere for now and see how loud it is.  I'll look for cops before I get on it. Besides, it might sound cool and it'll scare the hell out of the competition!
Hell if I ever get on this thing at all, noise or no noise I will have to watch for cops. In first and second its gonna lite up the tires for sure...anything in third or above and I'll be speeding anyway so I can't really win.
I think what I'll do if its too loud is plump it back into the down-pipe with a collector of some sort. Not a hard job though for future work.

Tom, you might want to add some type of structural support for the wastegate. That is one large mass cantilevered out past the up pipe, and combined with the engine vibration and road loads, I would expect a lot of stress on the wastegate pipe to up pipe connection. I don't know what real estate is available underhood....maybe you can run a thin tubular brace or strap down on an angle to the up pipe.

Numbers? Funny you ask that.
I'm not really sure, but my attempts at simulating a similar turbo with the dyno simulator are showing good numbers. The problem is these numbers aren't exact because I don't have the correct specs for the turbo to put into the program.
Oh yes, the numbers
It appears that with the intake and head work that I have done I should be looking around 375-425 HP.
