  I'm now considering the "ideal" to be more like 2 1/4 for an inch or so
and then going to 2 1/2.  I used a "weld elbow," 2 1/2 inch with a "special
order" 2 1/2 inch tight radius.  It's thick and heavy and probably overkill.
ID is great but OD gets in the way of bolting the flange to the turbo.
why I'm thinking of something a little smaller when I do the Rabbit.

  Yes, we didn't realize a boss came with the pyrometer so Dad took a
pipe coupling and ground it to fit the curve of the elbow.  Then he had them
blow a hole and weld it on when they built the exhaust. :)

  Tons of room.  It enters the pan about an inch + below the top.
