My suggestion is to get some small pieces of stainless steel to use as shims to tighten up the shroud around the exhaust pipes.
I doubt that high temp silicone would last very long.
Without seeing a picture of which part is loose and where it’s loose, it’s difficult to know what to suggest.
Can you send a photo?

I have a ’67 PA-28-140. The carb heat shroud has come slightly loose. It has a slight rattle, and I cannot tighten it any further. There are no cracks (yet) as far as I can observe. Was wondering if some high-temp silicone calk could be used to fill in the small gap around where the shroud clamps onto the exhaust stack header?
In general, this part seems to be a general headache for all of the other folks on the airport with similar aircraft.
