I don't think there IS an affordable "correct" way. Anything that
works is good. Is the silicone strong enough, or do you do the sheet
alum thing, like I do, and then seal around that with the silicone.
I'd love to have a good solution, but I figured the silicone would be
too weak and would not take the heat. I might try that next time.
The Hi-Temp Ultra Copper from Permatex is O2 sensor safe, and is formulated
to withstand really high temps (1200+degrees). This is why I like it for
exhaust work, since it was originally designed for that. I usually add a
thin coat to the HE pipe, then slide the donut on, add a little to both sides,
and assemble the exhaust. The side benefit of the silicone, is that it
actually keeps the muffler pipes from rusting to the HE pipes. : ) This allows
you to remove the muffler IF you need to, without destroying the muffler
(as I've seen others do in the past).
