Could somebody look and tell me what kind of hardware attaches the Y-pipe and its rear secondary turbo half. Are there studs coming out of the turbo outlet housings using nuts on top to hold them on? or bolts screwing into the turbo housings?

 

The 2 halves of the Y-Pipe aren't held together with anything, one half slides into the other and there is a rubber o-ring gasket to prevent leaks. If your talking about what the inlets are secured to the turbos with then it's studs with nuts. Pretty small one's too, 8 or 10mm I think.

 

I'm sorry, after rereading your post I think I misunderstood your question. Here's a pic that'll better explain it:



Sorry for the crappy Photoshop handwriting. Stud=Studs and Nuts, Bolt=well Bolt... Hope this helps.

 

Appreciate the info, I went to reinstall the Y-pipes after changing out the turbos and I thought I was losing it. I guess I forgot to remove the turbo outlet studs before I ship them to their new owner. The new turbos do not come with any studs. Once again off to the parts store!!

Thanks again,
André

PS They are 6mm x 1.00
