you won the battle but are going to lose the war.
What do you mean by this? I gotta know
It means you have to modify your online behavior at RR.
What do you mean by this? I gotta know
Folks are gonna tell you to vist the helpful hardware man in the future, whenever you ask a question.
Solution : the search function.
So we don't get confused, this is a wiseass comment.

Fighting words are written or spoken words, generally expressed to incite hatred or violence from their target. Specific definitions, freedoms, and limitations of fighting words vary by jurisdiction. It is also used in a general sense of words that when uttered tend to create (deliberately or not) a verbal or physical confrontation by their mere usage
Conflict was never my intention. I hate conflict. But I see that "deliberately or not" means one can still use fighting words just by being insensitive. Sorry Jacoub. I meant to open you to the suggestions given and tried to use persuasion, but it came off insensitive.

Any of the methods short of globbing on too much rtv will work. Why wouldn't it?

What's epoxy melt at?
http://www.loctiteproducts.com/tds/EPXY_5MIN_tds.pdf

On page 3, it gives two specs.....short term exposure and long term exposure service temperature after curing....

LT = -9°F(-23°C) to 120°F(49°C)

ST = -9°F(-23°C) to 302°F(150°C)

Couldn't find a spec. for Devcon 5-min.

Most of the Devcon over the counter ACE hardware Epoxy isn't good past 200F, and in particular does very poorly when up against alcohols, ketones, acids, alkalis. Maybe if you're burning gasoline, mineral or motor oil and can keep the exhaust really cool, then you'd have something!

Definitely not a product I'd consider here.

Good find....I agree...don't use devcon for this purpose

Guess whatever Loctite link pointed to is a little better, but what's the exhaust temp.?

I'd try to "lap" the exhaust header first, and then add a thin copper gasket if lapping didn't work.

At the bottom, Hansen claims ~200F.

If true, that rules out the use of Devcon.

PC Epoxy will hold up to 500F, and it is easy to fourm, easy to handle and easy to stick it at muffler
