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

The plate is not designed to go around onto the outside diameter. This would be just too much of a forming operation. It simply rests on the inside of the clamp and, when the clamp is tightened, it can't go anywhere. The sealant is definitely necessary to provide a leakproof joint. The sealant is good to 700°F. and it is very unlikely that the exhaust pipe will ever reach this temperature. Remember, it is out of the normal exhaust flow and would need a bit of time to get to this temperature if the manifold did happen to heat up above this temperature. So far, it has held up for the past year on the SDL. Only time will tell.
Worst case: You pull the copper plate and apply some fresh sealant at some point down the road.
