    Lava Exhaust Wrap Install and Test

    There are a lot of myths, malarkey and horse manure out there when it comes to exhaust wrap. The biggest pile is that exhaust wrap destroys your headers. This is a misconception that scares people away from using exhaust wrap to increase performance. When you wrap exhaust headers, more heat stays in the header pipes—which is what you want.

    Where the misconception comes into play is with what happens after the wrap is on. There are a multitude of headers out there and therefore a variety of alloys for tube material. Metal alloys have a minimum and maximum temperature rating for what they can withstand. Extreme cold has major effects on metal just like extreme heat does. That’s why aircraft aluminum is designed to withstand extreme cold way more than extreme hea

  2. Installing Your Heatshield Products Like a Pro

    Things would be a lot easier if all those exhaust pipes and manifolds were straight when it came to installing exhaust wrap or other thermal barriers to cut down on the heat radiated by the exhaust system. But all those bends are there for a reason, so you just have to soldier through it and do the best you can.


    Knowing what everyone faces when it comes to wrapping their exhaust systems in thermal barrier materials, we’ve put together some helpful videos that demonstrate how to cut and shape your Heatshield Products materials to make installation over bends in exhaust pipes and manifolds easier, along with some tips on how to actually install the product to make things easier as well.

  3. Ditch the Itch and Control the Heat with Heatshield Armor™

    Fiberglass itch—that annoying byproduct of handling typical exhaust wraps or automotive thermal insulators. What could be more annoying? Seeing someone take up two parking spaces for one car? Celine Dion singing Christmas carols on your doorstep? Clowns?


    Well, whatever might be more annoying, what you need is a thermal insulator to keep heat in the exhaust and out of the engine bay without giving you the itch. That’s why we came developed Heatshield Armor™ and Lava Header Armor™. These products control the heat without the use of fiberglass.

  4. Why a Flexible Exhaust Wrap is Best

    There’s more to picking the right exhaust wrap for your application than just looking at the temperature rating of a given product. You’ve got to be aware of a product’s resistance to water, oil, and other solvents things on a car are typically exposed to, durability against friction of something rubbing up against the wrap, but one that often gets overlooked is the exhaust wrap’s ability to maintain an optimal amount of flexibility, even after numerous heat cycles, exposure to the elements, etc. That’s where Heatshield Products has spent extra development time in the design and makeup of our entire flexible exhaust wrap line.


    The reason this is important is due to the natural laws of physics. When the metal piping of an exhaust system and headers heats from the hot exhaust gasses passing through it, that metal expands. In the reverse, after the engine is shut o

  5. Why Does My Exhaust Wrap Smoke?

    You’ve finished installing your freshly wrapped headers and exhaust, but a few minutes after firing up the engine, you notice wisps of smoke coming from the engine bay and exhaust. You open the hood and nothing is on fire, but your freshly installed exhaust heat wrap is smoking like it’s going to catch on fire. Not to worry—this is actually normal for newly installed exhaust wraps that haven’t yet been exposed to heat.


    Exhaust/header wraps are made with binders, which are specially formulated starches that give the wrap’s fibers some structure and lubrication during the weaving process. Once the manufacturing process is done, the job of the binders is complete, and when exposed to exhaust heat they tend to burn off, creating the aforementioned smoke after using exhaust wrap.


    Another question often asked is why cheap wraps become brittle after a period of time/heat cycles and can disintegrate. This is the result of
