Hi Gerard,

Wow, thanks for the info.  When I bought my 2-piece EM from Didi, I didn't ask for the studs.  I was going to try to reuse them from my old manifold, but they don't come out cleanly enough for me.  Since the manifold is new, I just want to get new studs.

The wastegate to downpipe hardware I'll just go with some quality hardware stuff I think.  That's a through-bolt situation, not a stud one, right?

Pretty soon my 4kstq is going to have a motor in it.  How soon it runs it another question.  I hope to be able to fit the downpipe in the car with the motor in place.  I've heard it's possible, but I've also heard it's a pita.  I just want to get the damn thing off the stand and be able to take down my cherry picker.

Thanks,

Ken
