J-B Weld ExhaustWeld 2" x 72" Repair Wrap

only few days is just crack

Worked as expected.

Ok. Well, I didn't expect a great deal for an exhaust bandage to be honest, but I'll happily eat my words at the moment. Had a rather hefty leak near a gasket joint, just after the cat, so a matter of a few foot away from the turbo. Instructions were very simple, and once you've managed to coat the bandage in goo (all in a package, so you don't get coated.. yet) The wrap comes out slathered in a white paste, and its easy enough to place and maneuver, but its a bugger to keep in place.. The aluminium foil strip, I found, was useless, and I ended up using zip ties whilst the resin hardened. I decided to let the resin harden for a few hours instead of running the car. But I do have to say.. wow... this stuff is rock solid and patched a hole for a while. Don't usually recommend things like exhaust repair bandages, but good lord.. if you need a temporary repair thats going to last.. get this.

This kit is a lifesaver for DIY exhaust repairs. I used it to seal a small leak on my tailpipe, and the results have been fantastic. The high-temperature fiberglass wrap is easy to apply—you just dip it in water and wrap it tightly around the damaged area. Once it cures with the heat of the engine, it hardens into a rock-solid, permanent cast that can withstand temperatures up to 1100°F. It completely stopped the loud exhaust noise and prevented further leaking. It’s a much more affordable and effective alternative to replacing the entire pipe. Highly recommended for any quick and durable exhaust fix!

My wife's car got a crack in the exhaust pipe which also has the front catalytic converter. I did not want to replace it just now, but I also did not want to the pipe to drop if the crack spread. This product wraps around the pipe and will provide supports to about six inches of the pipe. It cures well and seems extremely strong. It is easy to install, just wrap it around. It is good and sticky, has enough length for a few wraps of the pipe, and is certainly a cost effective temporary repair compared to running into the muffler shop. I've had this on her car for a couple of weeks and there is no leakage.
