I apologize for not taking any pictures however much like @KoolBRZ i was able to use the adapter with some modification. The smaller diameter pipe which is meant to take the exhaust donut had to be cut off and then the flange sanded/smoothed.

Once that piece was gone however the tapered side fit into the 3" flange of the header with room to spare. No more exhaust leak and there was plenty of room still even with it shifting the overpipe a bit.
