Default High temp rtv sealant for exhaust leak?

I have a 96 civic for my beater car and I have a exhaust leak. I was wondering if anyone knows of a cheap way to fix it so it will last a while?
I put a coupling in a month ago,used some quick steel and it worked great until today. They only thing I came up with with search is high temp rtv sealant. Iv used it on commercial hot boiler breeching before but not sure how well it would do under a wet car with the exhaust bouncing around.

Try some aluminum flue tape...any hardware store. RTV won't work.
