Remflex is all I'll ever use anymore. Just know once you have it on,its on no reusing.

I have re-used my collector gaskets multiple times. Sometimes half the gasket comes apart on one side of the collector, but I just reinstall it in the same position that it came apart from and no leaks. I wouldn't do it on the header flange though.
