Heatshield Products Exhaust Wrap can lower underhood temperatures by as much as 50 percent. Exhaust Wrap features a vermiculite coating that makes it capable of withstanding 1,200 degrees F continuous and 2,000 degrees F intermittent temperatures.
Lower underhood temperatures means lower intake temperatures, resulting in more horsepower and better fuel efficiency. Wrapping the exhaust system maintains hotter exhaust gas temperatures, decreases the gas density and allows the exhaust gases to exit the system faster via higher gas velocities. Increased exhaust scavenging is produced, helping to lower intake temperatures by literally pulling them through the cycle faster. That equals more horsepower.
Exhaust Wrap also keeps heat out of the passenger compartment and reduces heat damage to components.

Q. Why does your exhaust wrap have a lower temperature rating than (Brand) *** or *********?
Fiberglass has an operational/service temperature of 1000°F. With coatings this can be improved to 1200°F, and without own proprietary HPTC, it can be improved to 1350°F. We acknowledge advertising our fiberglass wraps to have a lower temperature rating doesn’t help us in sell over another brand. We strive to be honest in our operational and peak temperatures. While it is true the fiberglass wraps can sustain a flash temperature of 2000°F, this is for less than 30 seconds. The designed sustained temperature for fiberglass wraps with traditional coatings is 1200°F like vermiculite or graphite, with the proprietary coating for our Premium and Cobra Wraps, we can extend it to 1350°F.
Q. Why don’t you sell a spray on silicone coating for your wrap?
We are not in the silicone spray business. That being said, even if we were, we wouldn’t sell a silicone spray to begin with good quality wraps don’t need a silicone coating to work. While coating the wraps is not necessary, we do understand the desire to upkeep a certain cosmetic appearance, we can respect that. Instead of using a silicone spray (silicone is good for about 450°F continuous, sprayable silicone is good for 300F max) we would recommend hitting a local auto parts store. Walk in and grab yourself a can of exhaust paint in your desired color. Exhaust paint is a ceramic based paint (usually rated between 1500°F and 2000°F), it will last a lot longer than a silicone paint and work better too. Look for a brand like VHT or Dupli Color.
Q. People say wrapping your exhaust pipes causes them to rust, is this true?
A. No, fiberglass, basalt (lava Wrap), and silica (Inferno Wrap) are all naturally water resistant fibers. This means, they will resist and repel water. A properly installed wrap will actually prevent less moisture from touching the exhaust pipe. Pipes that are completely saturated, like in a flood or extreme driving condition would see some water getting through to the pipe.
Q. Why does my exhaust wrap smoke when it is new? Is this bad for me to breath in?
A. No, the smoke you see is a starch (often called a binder), the starch goes on the fibers when the fibers are still raw. This is to aid in the knitting process. The smoke you are seeing is the starch burning off during the first couple of heat cycles the motor. While it isn't harmful to breath in, we suggest avoiding it if you can, it stinks - don't hot box in your garage!
Q. I have heard soaking the wrap when I install it will cause it to shrink and fit the pipe better, is this true?
A. No, we are dealing with fiberglass, basalt, or silica fibers here, not cotton. These fibers don’t shrink like some of your clothes would. Soaking may cause a tighter fit because wetting the wrap significantly reduces the amount of fibers. With fewer fibers floating around, you are less itchy, that allows you to take your time and get the wrap nice and tight. Patience is key when wrapping any pipes. Wetting it will also aid in causing the wrap to “stick” itself better when coiling around a pipe, again aiding in installation, but technically it does not shrink to fit the pipe. Soaking is not necessary, you can dampen the wrap with a spray bottle, but soaking is not necessary.
