Design Engineering Black Titanium Exhaust Heat Wrap with 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

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

This works if you prep yourself by using masking tape on any cut ends, to include taping and cutting down the middle of that. This stuff will fray easily because it is made of lava rock and unlike the other material, non titanium, it doesn't stay together as well as expected. The taping addresses this. Just be sure to secure with perhaps hose clamps and then cut the taped ends off. I used this on a UTV header and pipe, along with a motorcycle header pipe. I found that on the motorcycle that the wrap is thick enough to fill the gap between the pipe and heat shields so I plan to install a second clamp under the first ones connecting the heat shields to create an offset and to allow air to flow between like OEM. Otherwise the heat just transfers to the heat shield and cooks your leg. I'm not sure how well this is helping on the UTV as i have radiator fans also blowing hot air directly onto the oem air box making it hot and impacting the air the moves through it. Be sure to wear some old gloves as the titanium will cause micro scratches in the skin, leading to irritation.

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

Goes on easy and looks nice.

Needed to wrap an exhaust hose that was too close to coil spring that has an air lift bag in it. The wrap was easy to use, cut and clamp with hose clamps.

The wrap contains asbestos-like fibrous material that poses serious respiratory and health risks, particularly during installation and removal. Cutting, handling, or disturbing the wrap releases fine particles that can be inhaled and cause: Mesothelioma Lung cancer Asbestosis Other chronic respiratory diseases The manufacturer's warnings are minimal, and many users are unaware of these hazards until after exposure. While this product works well mechanically, the health risks are substantial and often underestimated. Workers, DIYers, and mechanics should weigh performance gains carefully against potential serious illness. Proper respiratory protection during installation is essential—consider whether this product is worth the risk when safer alternatives exist.

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

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