Does anyone think that jb weld can stand up against the hot temps of the inside of a downpipe? I want to weld a little lip onto the thing , because air is leaking through their and the o2 housing. I had a dp made at a local muffler shup and i was comparing it to the stock on and i noticed there was a little lip on that one that kind of tucks into the o2. Any help would be appreciated.- Thanx

I doubt it. I have some JB Weld on the valve cover but I think that's the extent of the heat it can take.

Do you know if theres perhaps any kind of epoxy that could withstand exhaust temps? Or anything besides welding?

Qualco muffler, joint and crack sealer.

there is this stuff called qualco that is a exhaust joint and crack sealer that works pretty well. I had a few leeks around my o2 sensor and i put some of that stuff on there and it has held up for about 4 months now. I am not sure what you are really trying to due but for little leaks this stuff works pretty well , i think you could buy it at auto zone or maybe a muffler shop.
