Whoa, I said it looked elegant, not that it was the 100% best solution.
:)  Ideally, I think you'd want to have a 2.5"-to-3" flare *right*at*
the turbine outlet, but that's not exactly practical, is it?

Basically, it's been established that the downpipe will be 2.5" at
one point, either at the turbine outlet only, after the first bend, or
somewhere further down the line.  My question is whether immediately
flaring after the first bend *really*is* any better than just waiting
till the flexpipe, as Jay Stewart said.  I think from your swizzle stick
analogy, the answer is no...I think.
