Design Engineering Titanium Exhaust Heat Wrap 2" x 50' Lava Rock Technology

Hi Folks Greg 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) and a 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 and smoothed 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 and the 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 and so 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, so I 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; so I 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.

Very happy with this wrap. Have had it on my bike for a couple of thousand miles. This wraps easier and looks better than cheaper versions. Feels less itchy than others. It is easy to install if you soak it it hot water. Have not had any stray fibers and still looks good. Hardware was not included but used a wide stainless hose clamp. The thin stainless clamps work better for other applications

Used this on my downpipe and it made a noticeable difference in under-hood temps and heat soak immediately. The material feels much higher quality than a random fiberglass wrap, and it's pretty flexible. It's held up well so far, definitely worth it if you're trying to manage heat.

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.

Wow I bought the right wrap. Great price and quality. Bought red on ebay and it lost the color. This stays spot on as the color goes. Highly recommend

Very nice product..its nice you dont need to wet this stuff down like the other stuff. It likes to Frey at the ends so I suggest sharp scissors and black tape the end while wrapping so it dont string apart and dont accidentally push in the center while trying to wrap/stretch or your finger separates the webbing design and makes it a little ugly..same with edges, be gentle so it dont snag on things or it freys easily.

Very good product, have to watch youtube video how to cut it with aluminum foil. No need to keep in water for 2 days, make sure you keep it as tight as possible

The first thing I noticed when I opened the package is how cool this stuff looks. It looks sort of like carbon fiber. In reality it's made of very thin strands of metal bundled in threads and then woven together. [Update: I tested the temps with an infrared thermometer and I'm not extremely impressed. Even with two layers of the DEI wrap, the temps ranged from 350-500F on the wrap itself. I can't say how this compared to before I wrapped it though since I didn't take the temps. But I expected it to be lower.] The downside is that it seems to fray if it gets caught on anything. The part I was wrapping was in a really cramped area so after many feet of wrapping some parts started to fray, particularly the ends and sides, but if a thread in the middle gets caught it will pull out in a loop and distort the area around it, and you can't fix it. If you've got room and you're careful you could probably avoid the problem by being careful not to let it catch on anything or move it around too much so it rubs on itself or other stuff. In my opinion this product could really be improved by just sealing the ends and possibly the sides. It comes with the threads on the ends cut so they're just hanging there waiting to unravel. The sides are interwoven though so it's not as big of a problem. Another slightly less serious problem is that, although it's not fiberglass, it still has some of the same irritating effects. From all the microscopic strands fraying you find yourself itching certain spots a lot presumably from the them acting like glass strands and sticking into your skin. I can't say how safe it is to potentially breath these strands either, but since they're metal I'd assume they wouldn't be as airborne as fiberglass, asbestos, etc.

This stuff works so well that my car doesn't warm up as fast in the cold of Canadian winters. Easy to install (if a bit time consuming, but all header wrap is the same in that respect), and looks very attractive once installed. Under-hood temps are lower with my aftermarket header and this wrap than with OEM manifold and heat shields. I would definitely recommend this to anyone in need of good looking and effective header wrap. One thing to keep in mind though: it may be helpful to buy a roll of 1" wrap as well to do the runners that are in tighter spaces. Also, it should be noted that rather then buy the stainless zip ties from DEI, you can get them in the zip tie aisle at Canadian Tire for $6.00/10 ties. Thank me later for that little piece of advice!

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.

good, but does discolour over time. mine has gone a kind of gold colour (which I don't hate)

Works well as a heat shield
