Do you know why specifically a w-body downpipe doesn't work with the
Bonne? I have a w-body 3" downpipe here and it matches up identically
to your Bonneville downpipe.

Only thing I heard was I thought they didn't have the same positioning. Therefore if it mated up..it would be in the wrong position for the catalytic flange.

The flange of the GP dowpipe/cat is like 6 inch further to the back of the car.
It mean the flange come in the middle of a stock bonneville SSEi cat.
It need to be custom fit, like the SLP headers kit for GP.
