Design Engineering 010126 Titanium 1" x 50' Exhaust Heat Wrap with LR Technology

Hi FolksGreg Muncer here with Advanced Fleet Specialists of 37 years.I have a 1988 Chevy Caprice that is in great shape.The exhaust pipes and muffler needed 6 repairs.I search this product down;not wanting to replace the exhaust system.I followed every direction and added these things.1) I scrubbed an area around the repairs about a third away around the pipes,with a stainless steel wire toothbrush, and with Clorox Clean Up (spray) anda spray water bottle to thoroughly rinse the area after the wire brush and soapy bleach scrubbing.Then I quickly wipe the area mostly dry with a paper towel so it did not flash rust much.2) I tape measured the repair area to make a patch about an inch longer than the ends of the repair area.3) I bought off Amazon here, one roll of " DEI 010129 2" Titanium Exhaust/ Header Wrap - 15' " for $14.95.This 2 inch wide exhaust wrap was a dog's great fetch, ("a cat's meow" ha ha),I took the Muffler Putty " Permatex 80333 Muffler and Tailpipe Putty - 4 oz. " , available here on Amazon also,and needed it (which mixes it just prior to use), like the directions said.I screeded the packet to the edge where you cut the packet open, then I cut only about 1/3 the end off,to be able to squeeze out about a 1 inch wide squeeze out of the packet.I squeezed the putty onto the measured and cut exhaust wrap mention above.I squeezed the putty onto the middle of the 2 inch wide tape all along its length.I then took a stiff piece off plastic, for a putty knife andsmoothed the putty over the tape, covering every edge.(I had laid the tape on a cardboard box to dispose of the mess made on a workable disposable surface)So, spread the putty thoroughly a little less than 1/4 inch thick on one side of the tape.4) With the tape spread with putty, I took my water spray bottle and wetted the repair area again.This time I only dried it very lightly, leaving it wet but not dripping.I dabbed up the drips with a paper towel.I then place the putty side of the tape against the wire brushed and wetted repair area;where the puttied tape patch, hung over the repair area about an inch on each end.I used disposable latex gloves and so with these gloves on,I smoothed the outty all over the tape which brought some of the extra putty to the edges of the tape.While smoothing the tape out, I had some putty come through the tape that is a little pores.(Careful to leave the center of the tape humped up a bit on its center length,so as to leave a good thickness of putty over the holes in the pipe or muffler).Extra putty from the packets can also be used over the outside of the tape to seal up the pores tape.Smoothing over the complete tape patch and its edges with putty makes a smooth cast like product,just like a cast use for a persons broken arm, except this cast is good for extremely high heat.5) Once you get your patch smoothed out on the repair area,I set a 1500 watt (small heater withing an inch of the surface of the wet patch.I found that the patch had to stay as hot as this heater would make it, for at least an hour or longer is better.(I had one place that I could not get the heat close enough to make the pipe hot for an hour and,when I drove the car (without giving it much gas) the patch had not sufficiently hardened andthe path lift off one end and the exhaust was escaping out the repair hole again)>Point is make sure you heat the patch good for at least about an hour.I found the heater made the patch and pipe hot enough that you could still touch it without burning your hand but,probably you could not leave your hand on the hot patch more than a few seconds without burning your hand.This should give you a good idea as to how hot to make the patch.It could even be a little hotter than this, although I like a slower curing process so,that it does not bubble up from too quick of hot heat causing the putty to boil before it hardens.Keep in mind that this tape over the putty slowes down the drying process andso the heater and the whole hour heating the patch seems to become absolutely needed.In summary this is a fantastic product and the tape really helps to bridge the gaps and maintain a real good consistent thickness of the repair.I used 3 packets out of the 4 packets that I bought.(Each of these purchase packs contained 2 packets inside each pack, soI used 6 little packets altogether.)Each tape patch average about 8 inches long and was applied long ways onto the pipe.I did not wrap the tape patch around the pipe except for one of the repairs that required it.The 2 inch wide tape came in a 15 foot roll and I used a little less than 5 feet of it.I paid $3.40 a pack and used 3 packs so I used about $10 bucks of putty and $5 bucks worth of the tape; soI used $15 dollars of product to make 6 beautiful patches. (I wasted some, when I did not let the one patch heat up hot enough and long enough).Use a heater, wire brush the area and get any greese off the repair area with a soapy bleach. Rinse it well with water (the putty is water based),pre wet the repair area just before applying the wet patch.My exhaust system was strong before I began and was being held firmly by all connections and exhaust hangers, but every pipe, muffler and resonator require a sizable patch and so it this $15 bucks worth of muffler putty and 2 inch wide tape save me the best part of $1,000. I feel confident I will not have to replace this exhaust system for another few years. Thank You Amazon, Permatex and Design Engineering; maker's of the 2" Titanium Exhaust/ Header Wrap - 15'.Happy Motoring, Sincerely Greg (I still spent 6 hours repairing the 6 areas) but just paid $15 bucks.Both these products, the putty and the tape were good up to temperatures of 2,000 degrees, oh yea.

This product so far has not change. Colors seems to be working well what is easy to rap after removing my pipes

It seems to work well but I Normally don't have a problem with home fiberglass . This stuff is on another level!!!! Had surgery to remove a piece of fiberglass in my hand it gets In your clothes buried in your hands. Warning!

I recently built my Mazdaspeed 3 and with the new headers I was getting a lot of heat under the hood, like extreme heat. Bought this wrap hoping to contain some of this furnace emanating from the header. My wife and I, yes my wife who is more mechanical than pretty much all of the “guys” I know, wrapped each header tube per the instructions. Be ready to bath in fiberglass cause it gets everywhere BUT this wrap dropped my under hood temps by about 30-40°. Looks great and works really well. If you’re having temp issues from exhaust this is a must have.

I've wrapped 1 Turbo header and by the time I was 1/4 of the way into it I was itching like I had been messing with fiberglass. I bought this specifically because it stated to be made with the LR technology and not Fiberglass. Inlaid more for this product because I didn't want to deal with the Fiberglass issues.

Durability and heat dispersion are great I give it five stars...only thing is the color faded alittle faster than I hoped but I don't blame it when it's on a piece of metal that constantly gets to 800+ degrees, 5 STARS!!!

If you're hesitant to buy because some people are leaving reviews about the product being fake, I can assure you that those reviews are either false, or they bought the product from unsavory third-party sellers. Not only did it come in its original packaging, it also did not unravel after trimming it. It is true, however, that it thins out to about an inch when you stretch it tightly. And also, you should do this kind of work outside, with gloves and a mask. I pushed in the fabric very hard with my finger and it did not come apart at all. The 15 ft roll was just the right amount of material for my application as my extension pipe sat a little too close to the gas tank for my liking. Thanks to this product I now have some peace of mind while driving.

3 stars on ease to install due to not coming with ties. Although it shows that it doesn't, it should, maybe 3. The product has changed a bit, idk if it's the weaving process, but it unravels at will very much. I lost a few inches due to this. Still a good product, overall 4 stars

Correct PPE before installingAwesome product works well nice thing is made in USA and they stand behind it

Used this to wrap my headers and y pipe because of a heat soak problem with the starter. Easy to use. Did not come with ties purchased separately. Headers wrapped out of the car. Would not recommend doing so with them on the car. Y pipe done on the car but access was open. Watch the available videos. They help a lot. Good product. Quick delivery from vendor. Heat soak problem solved using this, starter wrap and a metal heat shield.Product stinks on initial start up but now is fine and looks pretty good installed.

Great quality, read other reviews first, definitely easy to use and look great 👍

Product Quality is good. Fuss free installation...no lose threads or damage. Not yet seen a noticeable difference in Performance. Still very early days and hence just the looks are good enough for now. Will edit the review based on real world performance after a month or two.

Wrap went on easy . Great product. Used on Corvette side pipes - leg saver .
