Downpipe Leak

#1
Hi,
I really hope someone has some answers.
This is a really frustrating problem. My car has an ATR 2.5' downpipe. The problem is where it meets the turbo. It has a doughnut like the stock downpipe. I have changed doughnut several times. However, it doesn't fit tight in the turbo and it I move the cat up and down (moving the downpipe) the leak is really bad. This would explain why under boost the leak is so bad. Do I have the wrong doughnut? Anyone have any suggestions?
Thanks!

Years back did some in that area and that donut seal or gasket was in back shape and it was really late for a parts runs so I used foil paper. Hope that helps for a minute.
