Header Wrap is the high-performance heat wrap for your big power race car. If you are tired of that 2,000-degree F “Brand X” header wrap that becomes brittle and falls apart all too quickly? Heatshield Products Inferno Header Wrap™ solves the problem. It is rated at a true 2,000 degrees F continuously and stays flexible, with a long life. Simply put, there is no insulating wrap on the market that will withstand higher temperatures and last longer.

Fiberglass and basalt-based (crushed volcanic rock) exhaust wraps have their place, and we rate our products with these materials at a 1,200-degree F operating temperature. To function in serious heat, our Inferno Wrap™ is made from silica fiber, making this header wrap soft, strong and flexible while operating at its designed continuous temperature of 2,000 degrees F. In fact, this wrap can withstand intermittent temperatures of 3,000 degrees F, making it the only wrap to use on your forced-induction or racing application.

The Inferno Header Wrap™ stays so flexible, you can unwrap the header when needed after hundreds of heat cycles—even after extreme temperatures have been reached. Installation is simple: Wrap or “coil” Inferno Wrap™ around the header tubes, using overlap to hold it in place (like a hockey stick or tennis racket grip) and use our Thermal-Tie™, hose clamps or wire to secure the ends in place.

Header and Exhaust Wrap Calculator


This calculator is a tool to estimate how much exhaust header wrap you will need for your headers, downpipe, or exhaust system. Calculations are a guide only! Actual usage will vary depending upon installation. Tighter installation of exhaust wrap on the pipe results in smaller header wrap needed.


All fractions should be in decimal form:
  • 1/8 should be 0.125
  • 1/4 should be 0.250
  • 1/2 should be 0.500
  • 3/4 should be 0.750
  • 7/8 should be 0.875


  • 3/4"- 2" pipe OD use 1" wide wrap
  • 1-3/4"- 4" pipe OD use 2" wide wrap
  • 3"- 4" pipe OD use 2" or 3" wide wrap
  • 4"- 5" pipe OD use 2", 3" or 4" wide wrap
  • 5"+ pipe OD use 3", 4" or 6" wide wrap


¼" Overlap is recommended for automotive applications, a 50% overlap is recommended for all motorcycle, UTV, kart, marine, heavy duty and industrial applications.

Why does my header wrap get brittle and fall apart?

When exhaust wrap exceeds its designated working temperature, it will crustalize and become brittle. The Inferno Header Wrap is the only true 2000F exhaust wrap that can sustain short term temperatures of 3000F.

I don’t like the color can I paint Inferno Header Wrap?

We understand the need to customize your hot rod or race car. You should not over pay for some goofy silicone spray. If you want to customize the color of your exhaust wrap, 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 degrees F and 2000 degrees F), it will last a lot longer than a silicone paint and work better too. Look for a brand like VHT or Dupli Color.

I hear 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.

Will Inferno Header Wrap smoke when it is new? Is this normal for exhaust wrap to smoke?

Yes Inferno Wrap will smoke for a while on a fresh install. It is not harmful to breathe in, but it does stink. Please do an initial start up in a well ventilated are, or preferably outside! The smoke you see is a starch, the starch goes on the fibers when the fibers are still raw. While it isn't harmful to breath in, we wouldn't advise it, it stinks - don't hot box in your garage!

Does soaking the exhaust wrap when I install it cause it to shrink and fit the pipe better?

Short answer, no. We are dealing with water resistant fibers like fiberglass, basalt, or silica- not cotton. These fibers don’t shrink like some of your clothes would. Soaking in some cases cases may help control loose fibers while wrapping. 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.
