Extended Information

The Exhaust Insulating Header Wrap was developed over 20 years ago by Thermo-Tec. Exhaust Insulating Header Wrap is an innovative way to create more horsepower and reduce under-hood temperatures.

Wrapping headers maintains hotter exhaust gases that exit the system faster through decreased density. Increased exhaust scavenging is produced, along with lower intake temperatures. Exhaust Insulating Wrap withstands continuous heat up to 2000°F, and contains no asbestos.

Thermo-Tec exhaust wrap will not over-insulate a system when properly installed due to a proprietary coating developed by Thermo-Tec - Thermal Conduction Technology (TCT) - that conducts heat across the wrap's surface. This coating controls heat build-up and dissipation.

Sold in a 1 inch wide by 50 foot roll

How exactly does our technology work?
Think of exhaust gases as a piston moving down through the tubular system. As each pulse travels down the system, it creates a vacuum behind itself. The negative pressure behind each, is the scavenging effect. As the velocity of the pulses increase, the negative pressures also increase. As you have an increase in velocity, the length of time that you have a negative pressure in the system is increased. The net result of higher velocity to assist in scavenging is increased performance of the intake and exhaust system. Maintaining higher exhaust temperatures throughout the system increases performance in many ways.

Think of exhaust gases as a heavy liquid such as an oil additive. If the liquid were traveling down a tubular system in a cold state, it would move very slowly. If you were to heat the liquid, the density of the fluid changes. The liquid responds to the heat increasing Its velocity. Exhaust gases respond In the same manner. Higher temperatures in a system increases the flow of the system. If the liquid is allowed to cool in the system, It slows down the flow of the liquid. By this Illustration, you can now see the importance of maintaining higher temperatures in a exhaust system.

The Incoming air charge increases due to many different factors. First, the lowering of air induction temperatures and cooler fuel coming into the engine will increase horse power by over 1% per Degree drop In temperature. Other areas of performance are Improved by the increased scavenging effect. Increasing the scavenging effect of the exhaust allows the engine to breathe more efficiently. A engine in many ways is like an air compressor, the pushing of exhaust gases from the combustion chamber creates a condition called pumping losses. This is the loss of power due to the piston pushing these exhaust gases Into the system and out of the system. Increased scavenging not only lowers pumping losses but also allows more efficient clearing of exhaust gases from the combustion chamber. This means cleaner air fuel mixture, this means power. The increased scavenging effect of the exhaust also benefits the intake of air & fuel during the overlap phase of the intake stroke. During the overlap phase, both the intake & exhaust valve are open. The exhaust gases create a vacuum effect which pulls the air fuel mixture at a higher velocity through the intake. As you can see, there are many benefits to the use of our product, lower cockpit temperatures, lower under hood temperatures. These all mean increased life of electric & electronic components.

Exhaust wrapThermo-Tec is a one of a kind product. Through a proprietary treatment of inorganic materials, the material develops the unique ability to conduct heat across its surface. This provides distribution of heat throughout the system providing insulation without creating hot spots. The conductivity of just the right amount of heat to combat the problems of the heat radiated by an exhaust system were developed over a period of 3 years of research and development. The specific make up of the Header Wrap was developed as to not over insulate the system and provide just the right amount of Insulating properties. It is very important to retain only a specific amount of heat. We caution the use of any products said to be used for this purpose. The specific make up of Thermo-Tec Header Wrap Is a delicate balance of high temperature materials blended to control a accurate amount of heat dissipation Beware of any products said to be used for this use.
