Fiberglass Repair Kit Automotive Exhaust Pipe Repair Wrap 4" X 15ft (1 Roll)

This product was easy to use, need multiple wraps as the material is a bit gauze like so in order to seal an exhaust one wrap won't do. I wore gloves, but the product actually had a pretty decent cure time and did not get tacky right away as some reviews said. Towards the end it did, then got stiff and stopped adhering to itself,, but I was just triple checking the hole I had to patch by that point. I am thinking I had around 5 minutes to work with it. So plan your wrap and make sure you have room before doing it. If so, 5 minutes is plenty of time to use entire length. Nice and wide, which may seem harder to work with, but for sure covers pretty big holes. I had a hole the size of a quarter on the side of the pipe leading to my exhaust, more than covered it, and sealed it well as the noise the hole created is completely gone and the exhaust sounds stock again. It's been over 2 months now and still on and seals. If prepped right I think this could hold 2 halves of exhaust pipe together if supported ok. Well worth the price over getting it welded or totally replaced yikes.

I was honestly surprised at how much product came in the roll for the price. There’s more than enough wrap to cover a muffler and still have extra left over, which makes it a solid value. The material feels sturdy and durable, not cheap or flimsy. Installation was pretty straightforward, but you do have to work fast. Once you start wrapping, it’s best to keep tension tight and consistent, otherwise it can loosen up on you. I recommend having your clamps or ties ready ahead of time because once it’s on, you don’t want to pause too long or it gets awkward to manage. Wearing gloves helps too, since the fibers can be a little rough on your hands. Performance-wise, I had mixed results depending on what I used it on. On my Kubota tractor, it worked great. It noticeably cut down the heat radiating off the muffler and seemed to help keep things cooler around the engine bay. No issues with smell after the initial burn-in, and it stayed wrapped tightly even after hours of running. On the flip side, I tried it on my side-by-side (SxS) and that’s where I ran into problems. The wrap caused the exhaust to smoke quite a bit, and it just didn’t seem to mesh well with that setup. I ended up taking it off because the smoke was too much for my liking. Overall, I’d say this is a great value if you’re using it on the right equipment. For tractors, lawn equipment, or similar machines, it does the job really well. For smaller recreational engines like SxS, I’d be cautious. Definitely worth the money, just make sure your application is a good match.

Used it to fixed holes in the muffler of a 1995 MULE. Worked for the first few times riding before blowing out holes again. I wrapped it with some steel to cover the holes and after using it for firewood today it started blowing smoke out like crazy. This muffler probably only reached a few hundred degrees. YOU WILL CATCH FIRE IF YOU PUT THIS ON HEADERS OR MIDPIPES.

Set up time to quick.

It will get you thru for a few days if your looking for long term just cut out the bad spots on your exhaust and replace them you will smell the wrap every.tome the exhaust gets hot and depending on how close to the engine and how hot it gets it may start to smoke mine did and it was right after the catalytic converter

I knew I had a substantial hole in one of the two flex joints on left bank crossover pipe (K2500 pickup, 7.4 liter Vortec engine). When I got the vehicle on the ramps, I was shocked to see both joints 100% failed and the pipe hanging on only by the rough edges at the failure. It was Friday, immediately drove to town to pick up four 3" exhaust clamps thinking I'll figure out what to do later. But decided also to search Amazon for other products and found this stuff and ordered. Living where I do (far north Minnesota), I didn't believe I would receive on Saturday. But it was in my mailbox by 1:00 pm! One commenter suggested installing dry and then wetting. Good advice that I followed. I made a trial 4" wrap from some rosin paper to determine length. With my die grinder, I prepared the surfaces to remove most of the rust scale back to solid metal without having the pipe fall off on my head. The installation was easy. Since I had 15' of the stuff, wrapped each joint three times. I'm sure this will get me bye for quite a while. Very rigid. I was concerned about eliminating a flex joint, but noticed that all replacement crossovers have eliminated the flex.

Good quick Fiss will not last forever but works well for my application

Seemed good to start but only about half way through the roll was already melted to together. Was going smooth then suffenly ripped and stropped. Possibly bad batch or water got into the packaging. I was wrapping very fast.
