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

Very good product but sadly the repair didn't last as the hole was to big.

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.

Easy

Works well if instructions are followed

A bit short to get to the manufacturer's instructions. Only managed 3 turns, but managed to cover the repair.

Bought to fix an exhaust. It worked great. Was well sticky and was easy enough to apply

This stuff is perfect and can be used in many applications. It will seal any small holes in a number of pipes on your vehicle and once set properly is strong. It is likely you will end up with a hole somewhere else before this fails.

I have a Mx5. As you can imagine the exhaust broke off into two. As you can imagine it was loud, I’m 20 so can only imagine what people think when I drive by. The same night I stumbled onto this “your phones don’t listen to you apparently” it has all these promises. I ordered it as I though I might aswell give it a go. I followed the instructions step by step. Everything as told and made sure to let it cure in the right way. When complete it lasted for a staggering 4 days of inconsistent driving as I have a company car it snapped. It’s not too expensive so I can imagine people aren’t crazy about writing bad reviews but this is just bad. It didn’t last and has made more of a mess. If you want some advice buy a metal bandage with a jubilee clip. It will uphold its promises a lot more than this cheap junk

only few days is just crack

I tried the paste before this and it just cracked, this has stayed in one piece. It works great. Not much to say really. It cures on its own in a couple of hours or you can start the car and cure it quicker with the heat. I let mine sit overnight rather than rush it. Maybe that helps.

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.

Worked as expected.
