Exhaust wrap re-engineered from the fiber up - the original heat wrap made from crushed volcanic rock (basalt) fiber! Lava Wrap has all the same performance enhancements as a traditional heat wrap, but additional exhaust wrap benefits are the cool carbon fiber look and long life of the basalt fiber. The lava rock wrap fiber is 25 percent stronger than fiberglass wraps.

Wrapping 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 under-hood temperatures by as much as 40 percent, further lowering intake air temperatures and creating even more power.

Our Lava exhaust insulating wrap withstands continuous temperatures of 1,200 degrees F and intermittent 2,000 degrees F. 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, and still made in the USA.

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
  • ¼ should be 0.250
  • ½ should be 0.500
  • ¾ should be 0.750
  • 7/8 should be 0.875


  • ¾"- 2" pipe OD use 1" wide wrap
  • 1¾"- 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.

What is the best exhaust wrap for my car?

We really like the Lava Exhaust wrap for all naturally aspirated applications. Because the lava rock fiber heat wrap is so much stronger than fiberglass wraps and it is naturally chemical, water, and acid resistant. We believe this makes the Lava Wrap the best exhaust wrap for most applications.

How can I reduce fraying when installing my exhaust wrap on my header?

We recommend the fold over or spray technique. The fold over involves having an extra 1/2 to 1 inch folded underneath the wrap when you start it and finish it at the end. You may also use a high temperature clear engine paint to spray on your volcanic rock wrap then cut to eliminate fraying.

Your exhaust wrap have a lower temperature rating than (Brand) *** and other volcanic rock wraps showing 1800F?

Basalt (volcanic rock) 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.

Can I spray on a silicone coating for your wrap?

Yes you can, but do not buy an overpriced “silicone sealer spray”. Instead, visit a local auto parts store or order some high-quality engine or exhaust paint online. Don’t bother with silicone that needs to be reapplied every few months. We believe it is a gimmick to get you to buy more products

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 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.

Lava Wrap is smoking like crazy when it is new, is this normal? Is this bad for me to breath in?

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 wrap manufacturing 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! Do your first heat cycles outside. It will eventually stop.

How long does exhaust wrap smoke for?

Smoking time will vary. The hotter the exhaust system, they quicker the starches and binders wear off. Some applications last only 20 minutes, some vehicles with cooler running exhaust systems can last a few days

Should I wrap my air intake and charge pipes with exhaust wrap? The people over at *** said I can wrap my intercooler pipe with volcanic exhaust wrap, can I?

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. Look at our Thermaflect Sleeve, Cold-Gold Tape, or Thermaflect Tape. They shield radiant heat. 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.

Use crushed volcanic rock exhaust wrap on:

  • Exhaust pipes
  • Headers
  • Mufflers
  • Exhaust Pipe
