JB Weld?

[BS87]

Stupid question maybe, but does JB weld work on exhaust pipes? Or is there something like it for the exhaust? I have this tiny hairline crack in my muffler that is just bugging the hell out of me.

Jb weld isnt meant for that, but they do make shit that does.

Thanks. Crack isn't that bad, but just seeing it bugs me.

I would just have it welded up somewhere, pobly cost ya $10

Probably easier this way, plus the 2 shops around here that do exhausts are rediculous.

Jordan, it's Industro weld, or something, right?

I picked up a tube of exhaust cement a couple of weeks ago when I replaced my driveshaft. My muffler had a couple of cracks in it where the pipes entered it that were making the car sound like crap so I figured I might as well give this a shot before replacing it entirely. Turns out that it was a pretty good investment of $5. I just cleaned the area thoroughly with a wire bristle brush, wet the area slightly per directions and squeezed it on. I worked it into the cracks a bit just to be sure. They recommend letting it dry for a couple of hours before starting the car but it ended up being the next week before I finished the job anyway. So far there's no sign of the cracks expanding or of this stuff blowing out...

The stuff I got was hanging on a rack next to the exhaust patches at the local AutoZone.
