Thermo - Tec Exhaust Wrap

An innovative way to create more horsepower and reduce under hood temperatures. Wrapping headers creates hotter exhaust gases that exit the system faster thru decreased density. Increased exhaust scavenging is produced, along with lower intake temperatures. Withstands continuous heat up to 2000°F, and contains no asbestos. Available in 1", 2" and 6" widths.

Hi Heat Coating

Use Hi-Heat Coating to finish off a clean and well protected exhaust insulating wrap application. Protects the wrap from abrasion and harmful liquid spills. Extra resins and binders toughen the surface and help extend the life of wrap by protecting it from friction, and seals the pores to minimize the penetration of harmful liquids. Available in black or aluminum colors.

Snap Straps

Used to secure exhaust insulating wrap. The high temperature stainless steel straps have a narrow profile to fit tight spots, and can be cut to the exact length needed. Secure with easy-to-use slide through fasteners.

Header Manifold Blanket

Provides excellent heat  retention for exhaust headers and manifolds. Simply clips into place on the upper portion of the header. The fabric side of the material should be facing the heat source, and the aluminized side facing away; offering protection from abrasion and harmful liquid spills.

Thermo Sleeve

 A seamless lamination of high temperature fabric to a highly reflective foil which provides protection from radiant heat for hoses and wires. Ultra light weight construction provides more insulating than traditional bulky rubber coated fiberglass. The aluminized sleeving reflects over 90 percent of radiant heat, and is fireproof and oil resistant. Packaged in 3 foot lengths.

How Does Thermo Tec 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 pulse 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 high 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 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 increase the flow of the system. If the liquid is allowed to cool in the system, it slows the flow of the liquid. By this illustration, you can now see the importance of maintaining higher temperatures in an
exhaust system.

How does wrapping headers increase horsepower?

Wrapping the headers maintains exhaust gas heat within the header. This translates into more exhaust flow due to maintaining exhaust temperatures as it flows out of the engine. By improving the scavenging of spent gases, the engine breathes more efficiently. This reduces contamination of gases, thus allowing the engine to develop more power.

How much wrap is required to do a set of headers? 

Guidelines recommend: (1) 2 inch x 50 ft.roll for a 4 cyl., (2) 2 inch x 50 ft. rolls for a V6 or V8, and (3) 2 inch x 50 ft. rolls for a big block or 180 degree set of headers.

Why do you use only a 1/4 inch overlap and nothing more? 

Using only 1/4 inch overlap draws the heat from the motor but still allows the heat to evenly dissipate through out the system. If you use more than 1/4 inch overlap you may cause fatiguing due to hot spots in your tubes. 

Does the wrap overheat exhaust components? 

This area is not a problem due to the added flow of the exhaust. Increasing flow also increases the amount of heat extracted from the engine and manifold

When is it not recommended to use header wrap on cast iron
exhaust manifolds on a turbo engine?

Cracking on stock exhaust manifolds and housing has never been a problem. Manifolds to the turbo can be a problem only if extensive modifications have been made to the castings. These types of castings have a high failure rate even without the wrap being applied to them. This is due to the uneven wall thickness of the castings from the machine work performed to improve flow of the manifold. The heat
cycle generated could cause the cast iron to become brittle eventually causing cracking to occur.

Can the header wrap be used on a catalytic converter?

YES!

What temperature will the wrap withstand? 

2,000 degrees Fahrenheit

Does the header wrap contain asbestos? 

NO!

What kind of material is the header wrap made of?

Highly textured silica based fabric with a patented inorganic coating applied by a proprietary process. A heat conducting coating is applied with a binder to the surface to provide a equal amount of heat distribution. Limit 2,000 degrees Fahrenheit.

Does the header wrap retain heat better than ceramic coatings?

Yes. Ceramic coatings are made from inorganic compounds made of aluminum oxide or of zirconium oxide or coating of an intermetallic compound. These coatings are all very good conductors of heat and only provide corrosion protection..

Does header wrap increase power and improve fuel mileage? 

Yes. By wrapping headers, exhaust gas heat within the header is maintained. This translates into better exhaust flow because the hotter the exhaust gasses stay, the faster they flow out of the engine. By improving the scavenging of spent gases, the engine breathes more efficiently. This reduces contamination of the intake fuel air charge with exhaust gases. Thus allowing the engine to develop more power
with less throttle.

Why is it necessary to lean the motor down in most applications with the wrap? 

Air/fuel mixture is enriched due to cooler intake and increased exhaust velocity. Increased scavenging of the exhaust has an effect on the induction side of any motor. Clearing the combustion chamber more efficiently means more efficient flow of the incoming air fuel mixture.
