Gaskets for turboback install

Hey guys, pull the exhaust, from O2 housing back to check for an exhaust leak and coat everything in high temp paint. What kind of gasket is there between the O2 housing and the downpipe? Is it a donut style gasket? I know rest will need a 3" 3-bolt and a few 3" 2-bolts being the system in a Hahn racecraft system. Just curious about the O2 to DP one. Thank you much

How is your leak sounding? I have a tapping exhaust sound only when its under light load that I can hear, like going up a hill. I cant find where it is, and its making me nuts. I've even had my daughter stuff rags in the tailpipe to induce back pressure while I feel around to no avail. I'm probably going to change the oring, which is part number 12609878 if you didnt know yet, as well as the rear 3 bolt flange gasket as well. Mine doesnt sound like its coming from the exh manifold or turbo/o2 housing area but we shall see. Let me know your findings on yours?

Check turbo to manifold bolts. Had one come loose and made an odd sound from gasket vibrating
