That looks like a rubber o-ring and downpipes get wayyy hot. I'm waiting for my Res ARMs to finish at the CeraKote shop. If the flange isn't snug enough on the long pipe I'll make a heat resistant o-ring out of heavy duty aluminum foil. That will provide a crush-fit like the OEM turbo and downpipe gaskets have.
