Exhaust heat wrap can lower underhood temperatures by as much as 50 percent with exhaust heat protection. 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.

White Exhaust Wrap also keeps heat out of the passenger compartment and reduces heat damage to components.

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.

I’d like to prevent fraying on my exhaust wrap, what can I do

To minimize the amount of fraying when cutting exhaust wrap use two different methids. The first one is spray the end where it is cut with some clear engine or exhaust paint. You can also do the tuck under method, simply curl 1/2 to 1 inch of wrap and fold it under itself.

Is a fiberglass exhaust wrap good for a turbo or supercharged application?

It is best to use a higher grade of exhaust insulating wrap for a forced induction application. Many times you see a race car or a turbo charged vehicles with wrap that is flaking off or partially covering the exhaust pipe. Fiberglass wraps are only good for 1200F, when they get hotter than this for over 30 seconds they fall apart. Try the Inferno Header Wrap for these high temperature applications.

Will exhaust wrap cause condensation on my pipes and cause them to rust?

Condensation is a normal by product of an internal combustion engine, but that happens on the inside of the exhaust pipe. Condensation is not caused by exhaust wrap being on an exhaust system.

Is ceramic coating or a heat wrap better?

We say if you have the budget do both! Ceramic coatings can give a wonderful finish to your exhaust system and improve the longevity of them. The limitation to a ceramic coating, is that it is a coating. There is only a certain amount of physics and chemistry you fight with a coating. Wraps generally stop more heat than a ceramic coating.

Use exhaust wrap on:

  • Headers
  • Exhaust Pipe
  • Mufflers
  • Catalytic Convertors
