The WTF is this thread (FMIII)
My Tial is dumping to atmo, it's not that bad. Easy fix for you to get it installed easily that won't make you hate life. Some people say's it's wayy to loud. I don't see it being all that bad.
I'd be willing to bet there is enough slop in all the bolt holes that you could loosen everything (Turbo, WG, and DP) and get the bolts started then start tightening, It doesn't appear to be off by much.

No, I don't think it's going to bolt up. If it looks that close in the pics, then the pics are deceiving. I'll go ahead and spray the EWG flange bolts with some lube and see how much, if any, play it has (since it has to come off anyway due to deteriorated gasket). But it would have to move towards the dp and rotate about 2 axes.
It's really too bad. This downpipe looks really friggin cool.

I called FM and tried to explain the situation. Jeremy said "call back after the holidays." Jeremy wasn't aware of any special torquing order, and promised he'd email the pdf of the install instructions. He sent me an email, but didn't attach the file.
Ben,
I remembered that I had a 1.6L exhaust manifold gasket lying around so I measured it for you. There is exactly 41mm between exhaust ports. If your manifold has more, then it's probably a 1.8L one.

Yes, the flanges on the EWG and DP are the same. No, they don't line up. No, I don't think it's a matter of the DP being bent. Yes, it's probably not too tough to fix it, if one were inclined. Tom, I measured the mani against my stock 1.6 header last night. I want to say that the 1.6 header was 41mm port edge to port edge, and this FMIII was 45mm edge to edge. I'll upload the pics I took...
Also, I have a seperate FM/BEGi bell mouth T25 1.8 downpipe. It was new in its wrapper, but I went ahead and opened it and assembled it. It's a good inch or inch and a half longer than the FMIII downpipe, and the cat flange is at a very different angle.
I'm kind of positive that I have a 1.8 mani and a 1.6 DP. I have no other explanation.
