Did you notch the heat shield on the motor mount? I had some interference there on one of the headers and cut a little bit off so it would fit better.
No interference with motor mount whatsoever.

I'm sharing your theory that the downpipes are pulling it away from the head. Again, the flanges at that end are pretty bad as far as alignment goes.

If it were you--would you try for another cheap eBay set or give up and go for something hopefully better (bimmerbrakes or AA maybe)?
