MUFFLER TAPE TIGERPATCH

This is an extremely difficult product to apply and they need to go back to the drawing board on how people are supposed to apply this.The directions seem simple but in practice they aren't. It's so sticky that using your hands is out of the question, unless you have some strong solvents to remove the glue (Acetone, MEK, Lacquer Thinner, Brake Cleaner, etc). Even gloves are kind of pointless, they stick to it too. Peeling the wrappers off are another problem, there are three (one clear on each side, one brown on one side), those are ALSO sticky so you're trying to remove those while simultaneously trying to remove the sticky wrap from your hands, while simultaneously trying to wrap it around the pipe. I've seen comments about freezing it but don't know how that would work given the pipe has to be hot for this to be applied.Other than the annoyance of the excessive stickiness, some people give up at the beginning because of the opposite problem, they start sticking it to the pipe and it keeps falling off! Especially because it seems to stick better to your hand than the pipe! One helpful piece of information, do NOT expect the first layer to stick to the pipe by itself, it doesn't work that way. The tape sticks best to itself rather than an exhaust pipe at least until you're done installing and cure it. You have to take advantage of this. Hold the very start of the first layer in place (use one finger), use your other hand to start winding the patch on the pipe, when the winding gets back to where your other finger is holding it (meaning one full 360 loop), overlap it but off by one inch so your finger clears. Once you've wound it at least one full loop so at least two layers are stuck to each other and cinched it tight, you can let go with that finger and keep winding without holding anything.The easiest way to picture this is if you take a piece of duct tape and stick it on a horizontal surface, it can be removed easily by pulling it upward, in other words opposite the direction you applied it. If instead you stick a piece of duct tape on a horizontal surface and you try to slide it by rubbing it horizontally, it's virtually impossible to move, same concept.Other tapes may be easier to apply since they forgo the use of sticky adhesives and instead use epoxy gels, they remain liquid and non-tacky indefinitely and only harden and stick when heated (which is presumably after you're done installing it).In the end it did not work for me. I tried to use this to repair a complete separation of a pipe as if someone had cut straight through its diameter with a reciprocating saw (a bisection). Neither side was applying any leverage to the other, both were suspended in air, I bridged the separation with a tin can as a sleeve so that no load or bend would be applied to this product, the instructions tell you to do this. The repair was about 5" downstream from one of the catalytic converters on an Infiniti G35, the heat was probably too much for the patch to bear. When I checked the failed patch, it had indeed hardened into a rock hard sleeve but it looked like the heat had caused the sleeve to burn and lose adhesion from the pipe. It would probably work better for cooler engines (less revs, less cylinders, smaller displacements) and better for small leaks in exhaust components located as far downstream as possible from the hottest components which are the engine, exhaust manifold and any catalytic converters, the muffler being the most furthest since that's where the exhaust system terminates and is likely coolest. Installing it on a high rev 3.5L V6 engine as close to the catalytic converter was likely never going to work...

Wasn't sure what to expect with some reviews saying it sticks to everything and others saying it sticks to nothing. The answer is it depends on the ambient temperature as under 70f it has little to no adhesion but starts to get some stick once it's above 70.While the product does seem to work well if you can get a good even coverage over the leak point, it lacks the flexibility to reliably seal leaks on curved sections or intersections if there's any kind of ridge or difference in pipe widths. Use a fiberglass+epoxy type wrap instead, they're more expensive but the greater flexibility will fit far better to give an airtight seal.Also recommend to have a clamp or two as you need the heat from the engine running to get it to cure, but the air pressure may loosen the wrap before it can set and seal properly without extra support.

Works good

The first one a got worked great so I got another one for a different project and it doesn’t get hot enough to set up but I have never had any of the other problems people post about.

Perfect

you need to apply this when the pipe is warm to the touch to activate the adhesive on it... i let the car cool down for about 30 mins so it was warm to the touch without scalding my hand... wear some rubber gloves since this product is fiberglass or you will itch... with the pipe still warm, start to wrap the pipe overlapping it by 50%... once you get it on, use a heat gun to further melt the product on to create the bond with the pipe... since i had some bends, the patch kept loosening so i used some heat wrap on top of the tigerpatch and then secured it all with stainless steel zip ties...once that is all done, go for a drive to get the exhaust up to operative temperature... you will smell a burning smell from the tigerpatch... it is the fiberglass getting heated... i found that if i went for short drives, when i parked and got out of the car, i could smell it the worst... but i then took it on the highway to fully cure the patch... this basically resolved the smell since i think any of the stray fibers burned off and the patch hardened... so far so good

Fixes exhaust leaks, as long as the part if the pipe is straight, and has enough clearance for you to wrap it. This stuff gets STICKY and pretty hard to manipulate, once you start wrapping the pipe. But, it’s worked well for me a few times. It’s a temp repair, and only lasts a few months, but I’ve used the wrap over and over again, and haven’t had a problem. Every time I wrap the pipe, it fixes the leak and I completely forget about it. Only to remember 3-4 months down the road when it starts leaking again. I just keep wrapping it like a dummy, instead of getting it repaired correctly. But this stuff has worked for me, even though I’m dumb. Be dumb like me. You’re welcome.

lack of adhesion properties

This worked for about a week of maybe 4 hours of driving. If you looking for a long fix I would go to the shop and get it fixed.. this lasted for like I said 4 hours max. Sound of the broken exhaust was gone. But the tape smelt burnt like right away. I left my vans internal air rotating in the van.

Easy to apply and sets up hard as a rock.

Good but does not last on muffler.

Didn't stick to the muffler, tie wrap and its works

When removing back paper. It did not remove properly. It had many pieces stuff on the back of the other.
