If you use this kit exactly according to the instructions it will work great. My leak was a hole about 3/4" wide and about 3" long, in a curve about two feet in front of the resonator tips. The exhaust is dual, but located about an inch apart. Just enough space to get the wrap through the gap. I prepped the surface with a wire wheel on my drill. I made the surface shiny all the way around the pipe and two inches on each side of the hole. So I had about 5" of pipe to wrap. I squeezed the pouch as directed and used the gloves. This stuff is a little drippy and messy, but if you are careful and operate slowly, you can get great results without getting drips all over you. The roll would not slip through the gap, so I had to unroll it to be able to pass it between the pipes. I'm working on a lift, so the tail could just dangle and not touch the ground. Anyway I was able to get at least five layers over the actual hole. It is like wrapping a mummy or an old style cast on an arm. After I got it wrapped, I changed gloves and did my best with the little thin strips of foil tape. I really think that is almost silly. It was barely long enough to really do anything and it will only stick to itself, and not to the wet "bandage". I wound up removing the tape after it cured. I started the engine and let it run for about 20 minutes and it was rock hard. With the location that it was, I could see it from behind the car, so after it cured for a couple of days, I gave it a coat of primer grey, so it would be less noticeable than the bright white under the car. I did the repair a couple of months ago and I have driven it a little over a hundred miles and it is still holding perfectly and sounds so much better than a leaky exhaust. And a repair like this was probably 30 times cheaper than replacing the exhaust on this car.

Works well. I secured both ends with worm clamps, one on each end. Kept the wrap nice and tight while drying. I didn't turn the car on to heat dry it as I didn't want any exhaust pressure pushing up against the wrap where the hole was. I just let it sit overnight and air dry. My leak was about 1"x0.5". Lots of comments about it not being 72" long. I think these reviewers are just underestimating the circumference of the pipes. Common exhaust piping range from 2" to 3" inner diameter, so larger outer diameter. Let's take 2.5" OD as a median example. Well, that's a 7.85" circumference. 72" divided by 8" is 9. You get 9 wraps around a 2.5" OD exhaust pipe. 2 wraps on each end, and 5 over the hole. Exactly as the instructions describe. I don't expect this to last indefinitely, and neither should you.

Good for a pinch and when you dont have any alternatives before you can get a real fix. Only thing to remember is that it is permanent and will mess up your pipes or surface if you need to remove it. My muffler shop had to grind this off to be able to weld the new muffler/pipe on.

This worked exactly as I needed. I used putty and paste to try to seal the ends of a connector after i cut the pipe and used a sleave to reconnect it. You could still hear put,put,put. It leaked! Used this on both ends of the sleave and it's as quit as can be. I think this stuff works best when both ends of the repair are supported. Without the support I think this would have broke in a short while.

My husband ran out of wrap before even getting two wraps over the hole. It takes 6.29 inches to go around a 2 inch pipe. They say to start 2-4 inches before the break/hole and that takes 3 wraps minimum because it is only 2 inches wide, plus you are supposed to overlap it. I only got 2 wraps over my hole and thay say 5 wraps minimum. The aluminum tape is a joke. It will not stick to the slimy/slippery wrap. Ben had to use aluminum electrical fence wire. Now I have to buy another kit and spend double the time! Forty plus years ago, my husband was wrapping exhaust with fiberglass tape with standard resin and it did better than this. JB Weld has performed well for me and my husband using their cold weld product, which has been fantastic. I expected more from this product. I HAD rated it one start but after a call with JB Weld, I raised to the 3 stars because it works good AND they said they would send another package for FREE!

fixed a broken exhaust flex pipe.. runs quiet now. cleared the O2 code and it hasn't come back since. my advice is to make sure you wrap it tight, plan your slack (don't unroll it all at once, plan each wrap and keep it tight as you make each one) peel the backing off the aluminum tape strip and wrap that around each side of the break to keep it wrapped tight on both sides of it while it cures. I prefer to let it dry for at least 10 mins before starting the vehicle to apply heat for curing.. personal preference. great product overall.

First off, this is not the seller's fault. The product is garbage as far as what they say it will do. I had a simple exhaust leak where the header pipes joined the exhaust. The sales pitch says it will seal exhaust leaks.. Cleaned the area of all rust and oil Applied per the instructions. First, that little tape they send is useless. Sticky tape does not stick to wet surfaces. I used zip ties as a last resort since the wrap wasn't going to stay on without something. It finally set up as they said it would. Felt kind of soft to me, but guess they knew it would be a little soft in the five layer section. Let it sit over night and started it up. It smokes just as bad as it did with nothing. Now I have to get this off and really fix the leak.
