Leaking exhaust

[Timgoheen]

I did a smoke test on my truck to check for intake and exhaust leaks before I install the fi system. I found it leaking where the y pipe attaches to the manifolds on both sides. I want to know what the best way to seal these is. The donuts were different from side to side as well. The pictures with 2 pieces is the passenger side.

The best way is replacement oem type pieces. Be sure to wirewheel/ clean the pipe well where they seat. Remove old carbon and boogers that would affect sealing

I can't seem to find the larger one that's in 2 pieces, unless the metal ring is a seperate part.

I believe the metal part is separate
