exhaust leak help

[Guest]

any one know of any way to seal the exhaust tubes ,where the head pipes go in to the collector ,on 4 into 1 , I tried a exhaust pipe expander but #4 , will not seal , and it is causing it to pop back till it gets hot , I tried to put pics on but keep failing ,.

I used Permatex Ultra Copper on a collector/header connection and a baffle/megaphone connection with good results.
A thin bead that stayed pliable for years.
You can get it anywhere.

thanks Steve , i will get some today, the only thing i could think of was to melt some lead in to the leak , but i like Permatex Ultra Copper better, lol
