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.

Had a 1/4” hole just after my muffler so I tried this wrap formula which turned out to be just as the site state. Welded secure around the hole area and does not leak even after high heat driving.

So this woven fabric similar to a cotton gauze roll is embedded with I will call an epoxy. Comes in a foil pouch because as soon as it exposed to air begins to cure. It cures up depending on the air temperature in about 4 hours. The one thing I didn't realize was it takes 24 hours before you're supposed to apply any considerable heat to it. I used this in conjunction with another of their products on my exhaust manifold that had a hole. I put their other product on to kind of fill the hole and then went over that with this to give it some strength to resist the exhaust pressure coming out of the hole. So due to the fact that I had to wrap around one pipe of the manifold I could not get enough wraps as suggested around the section. The product calls for five wraps and I may have gotten three. So I wish it was slightly longer because even on a large diameter exhaust pipe or muffler it would not be enough woven fabric. It conforms easily to irregular shapes being that it's like an Ace bandage. Comes with a piece of foil tape to hold it in place but that stuff is absolutely useless. The embedded cloth is slippery so that tape will not stick in place even if you tape it to itself. I guess the point of the tape is to kind of hold the fabric from slipping apart while curing. I just pulled the fabric as tight as I could as I applied it and made sure that the edges had the "epoxy" smoothed over them so that It may give a stronger bond between layers. This is not a permanent solution for any part of the exhaust system but it will get you through for a while if applied properly. It comes with gloves but the gloves are useless because they are so thin they tear easily. That would suggest getting your own gloves because this is quite a mess to handle due to the amount of epoxy that is embedded.

So what if it is a little messy...it should be so plenty of material for the cloth tape. They give a set of gloves for the hands and spread a little paper under your work and not a problem! This was my second purchase of this product for a hacked together exhaust for my portable generator to get the exhaust [ported out of the garage. Fist kit used and I let it set and it cured at Washington State ambient summer temperature. Last week there was a power failure and i finally used my get and the kit/patch held up just fine, though the aluminum tape came right off with the heat the wrap did not. But the pipe blew off in another spot so my second kit is to secure that splice. This time I used a heat gun to cure the wrap and did not bother with the aluminum tape. The wrap cured very quickly with the heat gun, it is not summer anymore so the extra heat was a good idea. Looking forward to the next power failure, I think I have it nailed! Great product J-B Weld!

The repair itself worked well and covered my hole on my Toyota Sienna, so I can't complain about the effectiveness of the product. However, I am disappointed by the amount of wrap included. The package stated that it contained 72 inches of wrap. My exhaust pipe has a circumference of roughly 7 inches, and the instructions recommended applying about 5 layers while extending the wrap 2-4 inches beyond the damaged area on each side. Based on those measurements, I expected to have enough material for approximately 10 wraps around the pipe. Instead, one package only provided about 4 wraps. I had purchased a second package as a backup in case I found additional damage elsewhere under the vehicle, but I ended up needing it immediately just to complete the repair as instructed. Because I was working underneath the vehicle, I did not stop to stretch out and physically measure the wrap, so I cannot say with certainty that it was shorter than advertised. However, based on the circumference of the pipe and the number of wraps I was able to make, the amount of material seemed significantly less than the stated 72 inches. The repair worked, but the quantity included did not match my expectations, and I had to use a second package to complete a repair that I believe should have been possible with one.

I trust the brand, and I've had exhaust repair wrap fail before, so I went with JB Weld. Most repair tape is slightly sticky and has resin that melts and then cures in place. This stuff is fiberglass roving (cloth) that's in a packet of premixed wet epoxy. It's slippery and goopy. It's messy and a little tricky, especially if you don't have a lot of clearance. That said, the wrap is pretty forgiving, so you don't have to be perfect with it. The lightweight nitrile gloves included will probably tear, and I recommend having your own better-weight disposable gloves already. Don't work with your face below the pipe, because you may drip epoxy. Wear workclothes accordingly, and clean off any epoxy that gets on your skin. The pack includes aluminum tape to hold the wrap in place while it cures. I didn't use that -- I used stainless steel zip ties -- so I don't know how well the tape works, but it's probably OK. The epoxy takes a couple of hours to dry unless you sit there with the engine idling to keep the exhaust pipe hot. It seems secure when it's dry. This stuff is rated for higher temperatures than most repair wraps, which is definitely promising.

Don’t waste your time with this stuff. My exhaust pipe broke at the weld. I figured I’d try this tape. Even though it was great for the first week, the tape ended up getting frayed and broke at the seam again. Save yourself the headache and don’t bother with this stuff.
