Design Engineering 010127 Titanium 2" x 50' Exhaust Heat Wrap with LR Technology

Installed on auto exhaust. Appears to have fixed an overheating issue. Is not hard to install but will get fibers all over you when doing. Wear long clothing and face protection. Immediately change clothing afterward. Durability unknown but looks like it will last so far.

Wrapped the exhaust on my Side X Side with this. Checked on several chat sites, this wrap seemed to be the best choice. Lots of people talked about cheaper products getting fibber glass all over, and having to wet the wrap to avoid some of this. Also coming apart after a few years. Only wanted to do this once, so spent the extra money. First time I ever did this, went very well. Kind of a pain to get the exhaust of, but the wrapping was pretty easy. Did it by my self, so it can be done by one person. Was in know hurry, so I took my time. Had to redo first pipe, didn't like how it ended on pipe, but figured out best way after that. Used metal ties to secure wrap, kind of a pain getting them tight but figured that out to. Made a big difference on the heat issues.

First, I purchased waaay too much of this stuff. I bought 100' and 35' would have been fine to wrap my set of shorty headers - so keep that in mind. I can't imagine trying to wrap anything like headers after they're installed unless you have some kind of street-rod with a ton of room. Turbo down pipes and other single pipes would probably be easier to do in place. After installation, I let the engine idle for about 20 minutes with the hood open and the *vehicle outside* - occasionally revving the engine to let the wrap do it's "smoking thing". After about 30-40 minutes of idling and light driving, all of the smoking and smell had gone away - and the next day there was no smell - which is nice. One tip: While letting the wrap "smoke off" remember to shut off your ventilation system in your car so that you don't pull the smoke into your interior - it's stinky stuff. Wrapping is pretty easy once you get the hang of it but expect to ruin a few feet while figuring it all out. I'd be a good idea to cut a few feet and practice. To keep the ends from fraying while working with the wrap, take some thin CA glue (super glue - but use the GOOD stuff you buy at a hobby shop or online, not the crap you get from a hardware store) and swipe a line across the point where you want to cut the wrap. The glue (if it's thin-consistency glue) will spread into the fibers and cure leaving a line about 3/8" wide. Cut through the tape in the middle of the glue stripe and you can wrap without it fraying (I found that surgical or EMT scissors worked the best for cutting). The CA glue will burn off later and not leave any residue or discoloration. In regards to getting the metal ties tight; you can either buy a tool that does this, or, use a needle-nose pliers and a flat-bladed screwdriver. To use the latter technique, feed the "tail" of the tie through the locking mechanism and pull it snug. Cut the tail off leaving about a one inch length sticking out. Take the pliers, grip the very end of the tail and twist, rolling the strip around the tip of the pliers. Now, take your flat-bladed screwdriver and place the blade *parallel* to the tie strip, one edge of the blade in the "notch" at the back of the locking mechanism and the other edge braced against the strip rolled around the end of the pliers. At this point, you can either add additional twist to the pliers or pry against the plier's tips to simultaneously pull that *last* little bit of tie through the locking mechanism while holding the locking mechanism in place to achieve a very tight closure. BTW, the metal zip ties you can pick up and Lowe's work perfectly and are MUCH cheaper than the "header wrap ties" that are marketed. At this point I'm pleased and I hope it lasts a long time. It's good looking stuff. As far as heat, I haven't noticed any more heat that I did from the stock heat-shielded manifolds - which is a good thing ;)

I purchased this by mistake, as I didn't realize the headers I had purchased already came with a roll of this exact product. I will say that it absolutely works, and does not discolor like fiberglass wraps. While I haven't put an infrared thermometer on it, to at least the hand it seems to insulate heat. I haven't noticed any higher oil temps, and my headers run around my oil pan (Subaru engine, original headers had fiberglass insulation packed around). It was pretty easy to cut and install, but a bit time consuming (as any wrap will be). WEAR GLOVES. Some will say you don't need them, those people are crazy. Even wearing nitrile gloves for most of the install, I was picking fiberglass out of my hands for at least a week. Avoid running this over your hands if at all possible. You will be very tempted, as it feels just like a fabric, until you do that. Then, it will just shower your hands with fiberglass splinters. Even a mask might not be a bad idea, as I was blowing some of this out of my nose. I would also suggest using stainless steel zip-ties, and considering their tool to get them tight. I used a pair of needlenose and a flathead screwdriver, and it was pretty annoying. I'm sure their tool works a bit better and makes for a tidier product.

Bought this product to try to eliminate some of the exhaust heat generated from the OEM header (catalytic converter removed) on my 2012 Harley-Davidson Tri-Glide Ultra Classic. The product was easy to install, after of course removing the header, and clamping it in my workmate (craftsman). I did not have to wet the wrap, but did wear rubber gloves as others have suggested. Yes some fibers did come off along the edges during the application process but that is the nature of the beast. I used SS screw type automotive pipe clamps to keep the wrap in place. Now, if anyone knows anything about the model trike I am using this on you will know it is a massive engine and it generates a lot of heat. The wrap did reduce some but did not eliminate it completely. As a matter of fact, on a recent trip to Bike Week in Ocean City Maryland, while sitting still in traffic for extended periods of time the heat generated from the header (right hand side) still felt like the inside of a volcano. So some people might say it is a waste of money. Especially since the chrome covers hide it. It does look very sexy if you like that look. On any older bike it would be a neat way to get that "race track" look. It does hold water and steams like crazy if you get caught in the rain, or after washing the bike. It takes about 3 - 5 minutes though for it to dry out so it's not a big deal. I would assume that on any other bike with a more open design, that is to say, with the pipes more exposed to air flow this product might be deemed worthy. On my trike, the exhaust is tucked away and therefore not much air gets to it. You may want to make this a last resort attempt though and try other methods of reducing the exhaust heat first. It does stay cooler to the touch than straight on metal though so if you have exposed pipes and have a tendency to burn your leg occasionally then it's purpose would certainly be better for that. For what it cost and since I was installing aftermarket mufflers anyway, installing this wrap was not to me, a waste of money or time. Your opinion might be different and I would respect that. The shipment arrived quickly and the product vendor is reliable. Rob

Wrap is excellent, so much easier to work with than the fiberglass wraps that need to be wetted while working. It does fray where cut, but the double wrap suggested to start with covers it well. The 50' roll was just enough to wrap my 4-2-1 head for my miata, which replaced the factory header / downpipe. The Tiewraps suggested by DEI don't work well, stainless safety wire works great and can look cleaner if planned for. It does an excellent job keeping the heat down, you can feel the heat, but can brush against the collectors and not get burned. Underhood temps are significantly lower. Will see how well it holds up to the salt / weather this winter and update this review in the spring.

I wish i wasn't a cheap *** some years ago and bought this instead of the cheap fiberglass garbage... so much easier and more pleasant to work with! got a 50ft roll and did my turbo header and O2 pipe, as well as the down pipe. Still used gloves as it was shedding some micro particles, but it was nowhere near as bad as FG stuff that will get in your nostrils/eyes/skin and itch for days. I'm sure it performs much, much better than the FG stuff also, judging by other reviews. Moral of the story: don't be a cheap *** like me and get you some of this nice DEI header wrap!

Listen a lot of people say that wrapping your headers doesn't make a difference. I can tell you from my experience that it does. The difference isn't like the car is going to magically be AC cold but the heat reduction is real. My feet no longer burn up and my cabin is cooler. I wrapped both my longtubes and it worked for me. However, there are two things you should note. Firstly, if you're wrapping headers like I was, make sure and buy around 100ft. And secondly, and I think the most important, MAKE SURE TO COVER YOUR BODY WHEN WRAPPING YOUR EXHAUST! Listen the fiberglass in this wrap is torture when it gets on your skin. Took me 3 days to get it out of my arms -.-' it felt like prickly needles cutting up my hands and forehands. Just be careful. The wrap works great though. I'll probably buy some more and wrap my x-pipe.

Excellent product

Il faudra voir à l’usage et dans le temps

Como siempre excelente producto ,la marca es garantía , no compres imitaciones de otras marcas, pierden su color con el tiempo y el calor....pero esta conserva su color por años y reduce la temperatura considerablemente ⭐⭐⭐⭐⭐

Item arrived on time. As per pretty much all other exhaust wrap I used, if you cut with a very sharp blade, you will get little fraying. Also, tuck the end under itself to finish before applying the clamps helps this also. No mess and no fraying after installing the same pieces three times until I got it just the way I wanted it. As far as heat retention, it is working excellently for me. I have a downpipe that was routed too close to the steering rack and was burning the dust boots. Now, after the wrap there is no sign at all of heat damage to the newly installed boots and the wrap is holding up great and in a highly exposed area to road debris.

Installed this on my motorcycle exhaust header to drop the radiant heat down. It's very flexible and easy to wrap. Couple of caveats, it will scratch paint if you drag it against it while wrapping, and wear a mask to keep the tiny fibers out of your lungs. Once this product cures from the heat of the exhaust, it's not coming off in any large quantities and makes a right mess.
