The original heat wrap made from basalt fiber (crushed volcanic rock), our Lava Exhaust Wrap™ has all the same benefits as header heat wrap, but with a carbon-fiber appearance and improved durability. The Lava exhaust wrap is 25 percent stronger than fiberglass wraps, giving it prolonged life.
Using Lava Wrap™ on a header and exhaust system maintains hotter exhaust gases, decreases gas density and allows the exhaust gases to flow through the system at increased velocities. Greater exhaust scavenging is produced, pulling intake gases through the cycle faster, helping to lower air-intake temperatures. This results in more horsepower and reduces radiant heat damage. Lava Wrap™ lowers underhood temperatures by as much as 50 percent.
The Heatshield Products Lava exhaust insulating wrap withstands continuous temperatures of 1,200 degrees F and intermittent 2,000 degrees F. Please note this is a real-world-tested rating, so beware of inflated temperature ratings of similar basalt/volcanic rock products rated at 1800F or higher. Basalt (the volcanic rock mineral) is molten (liquid) at sustained temperatures of 1800F. Make sure you are getting the original volcanic rock wrap with the honest temperature rating. Installation is easy: Wrap it around your exhaust pipe, using overlap to hold it in place (like a hockey stick or tennis racket grip) and use our Thermal-Tie™, HP Tie Wire™, or hose clamps to secure the ends in place.
Q. Why does your exhaust wrap have a lower temperature rating than (Brand) *** and other volcanic rock wraps?
Basalt has an operational/service temperature of 1200F. We acknowledge advertising our Lava Wrap to have a lower temperature rating doesn’t help us in sell over another brand, but we strive to be honest in our operational and peak temperatures. While it is true the basalt wraps can sustain a flash temperature of 2000°F, this is for less than 30 seconds. The reality is basalt has a sustained temperature rating of 1200F, molten lava has an average temperature range from 1700F-2200F, so question and verify any volcanic rock wrap saying it will sustain 1800F continuous.
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 450F 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 150°F and 2000F), 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?
Short answer, 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. However the increased exhaust gas temperatures would cause that moisture to evaporate relatively quickly.
Q. Why does my exhaust wrap smoke when it is new? Is this bad for me to breath in?
Short answer, no. The smoke you see is a starch, 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 when you first couple of heat cycles the motor. While it isn't harmful to breath in, we wouldn't advise it, 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?
Short answer, 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.
Q. The guys over at *** said i can wrap my intercooler pipe with volcanic exhaust wrap, can I?
Short answer, yes, but why would you? Intercooler pipe and air intakes generally are dealer with radiant heat, you are better off using a product that is a thermal barrier, not an insulator like an exhaust wrap. Take a look at our Thermaflect Sleeve or HP Heatshield Tape, that would stop heat from radiating into the pipe. In some cases where hot air has entered the intake system, wrapping it with a header wrap can do more harm to performance than good.
