I got my kit today and did the install per the supplied directions.
Simple process, what I did note was that the round copper plate did not actually cover the outside diameter of my exhaust. Just enough to bend/forum over the beveled end of the exhaust opening. After putting on my clamp there is an area of about 5/16 of an inch
that this clamp does not cover, the only thing sealing it well be the cooper sealant which was supplied in the kit, and my worry is it has a temp rating of 700 degree. Well this sealant hold up?

Thanks BC for your work
