Design EngineeringTitanium Exhaust Heat Wrap with Lava Rock Technology - 2" x 100' - Heat Wrap for Exhaust Pipes, Pliable Exhaust Wrap Tape, Withstands 1800°F Direct Heat & 2500°F Intermittent Heat

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.

I'd expect more from DEI, especially for the price, but it works. Just be aware that it frays easily after trimming

This really does work great and it is inexpensive but do NOT handle this bare handed, wear some leather gloves then you wrap the exhaust, I had slivers in my hands for days just like handling fiberglass. It does work great tho

Awesome product, works great on my Harley Davidson Breakout Big Radius pipes

Installed on 12 cyl. Cummins engine on our barge mounted crane. Lowered engine room temp by an an average of 37 degrees.Great product.

Received on-time, great product!!

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 haven't installed it on the exhaust pipe yet, but it seems like a quality product

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

J’ai utilisé sur mon Suzuki ltr 450. 2 ieme année et toujours ok. Je recommande de faire sécher après avoir nettoyé votre atv pour ne pas faire pourrir votre échappement.
