Exhaust Heat Shield Automotive, Embossed Aluminum Heat Shield Kit with 20PCS Cable Metal Ties for Muffler Exhaust Wrap, Heat Barrier,Car Exhaust Sheet (16" x 39")

Excelente!

I didn't use this as a wrap (so no need for the straps) but rather as a replacement for my rotted OEM muffler heat shield. This also helps protect the trunk floor of my car which had suffered rust damage likely as a result of the failure of the OEM shield. I was able to remove the rusted mounting bolts for the original shield and I used spacers in mounting this to allow air flow to hopefully keep the trunk floor dry.

There has been a long history of using wrap on headers and exhaust pipes. The originals were asbestos, but that has not been used for years after that was found to be a serious health risk.But over that time, other problems cropped up. Turns out the cloth wraps almost worked too good. Meaning they could retain too much heat in header pipes, causing them to fracture. And cloth wraps can hold moisture, causing bad corrosion.The flip side is some heat control is often necessary on exhaust systems. Case in point: I have one car where headers are practically up against AC compressor. On another, headers combine into dual pipes that pass less than an inch under dry sump pan, adding extra heat to engine oil.I got away from using wraps after too many issues with steel headers as mentioned above, and went to simple aluminum sheet and plates to try and help isolate exhaust heat from other places that needed to stay cooler. But then more recently I started using this stuff instead.No argument the dimpled finish looks really great. But is also serves a purpose, giving greater surface area for heat dissipation than simple flat material. I think it also makes it more flexible and easier to form to curves, but there is a limit.Sometimes be a bit creative by cutting in narrower strips and wrap those in sections. But this kit does include 20 stainless straps to allow for that, which is a good thing. Might want to do some preliminary design planning.I'm using some scrap poster board type material and masking tape to do mock-up prototyping first, and see how wide or narrow sections really need to be. But in some situations, you may have no real choice but to "crush" form this stuff to shape it.You can even cut long strips and do a spiral wrap if you prefer. One other suggestion: don't try to wrap really tight. Not so loose it rattles or shifts around, but just to the point where it makes surface contact with exhaust or other heat conduits. You can also use it to do the reverse: protect elements like intakes, and fuel and coolant lines that help those stay cooler, protecting them from nearby high heat sources.I like the thickness of this product. Enough to help do the job, but not difficult to work with. I do recommend using an abrasive cutter, although metal shears will work. I also recommend wearing some hand protection, as edges can be razor sharp, so be careful.When I'm done, I'll add some photos of finished work. But from some initial experiments, I think I'm going to be happy with this product. And I do have to say it creates a great cosmetic look, as in serious and professional. Just watch those sharp edges.The one question I can't answer yet is how much does it really help isolate heat, but not to the point of potentially damaging headers over time. Hard to imagine this won't help quite a bit, but has it limits with is a good thing. Otherwise, I do think this is a very good product and a very fair price.I routinely use replaceable Tempilable/Thermax strips in various areas to record high temp reached (including transmissions, brake calipers, oil coolers in and out, you name it). Those may tell me more over time, assuming there is a significant change that is readable by the strips. But it will be a while before I know anything from those.

Solid product

good item but would not fit where i need it to bend to

I got this for some car repairs after a minor accident and it is just what I needed. No complaints from me - I'm not the one who had to do the install so I can't speak to ease when it comes to that, but it has been holding up well on my car and I"m happy with it.

I used this to creat some heat shielding around my turbo, turbo manifold and wastegates on the race car. working great for keeping the heat where i need it and away from the places i dont want it. good quality and pretty easy to work with, there is a decent amount of material her for a number of different types of projects. i have some leftovers for replacment shields or maybe to make a few more. overall great value
