I have seen about 17 of videos like this one in the last couple hours, DIY guys fixing exhaust leaks with JB products, would it surprise you that only about a third of them have before and after sounds of the repair, ya know, so we can HEAR the repair, who cares what it looks like, it's under the car!!!

How long did it last? How about J-B Weld 37901

This stuff does not work if you use it close to the catalytic converters, it will break apart and fall off, I just wasted my time and effort using it but it may work on the exhaust areas like from the middle of the car towards the back because it won't be exposed to the extreme heat..

Furnace cement works better than jb weld

ATG & I say it's useless for catalytic converter where one has O2 sensor. Nothing work
Except throwing out $1, 800.00+ on parts.
