Thermo-Tec Exhaust Wrap 25mm Wide Natural Coloured Roll
Natural (Brown) woven glass exhaust wrap. 1 inch (25mm) wide. Available in 15 feet (4.5 metres) long or 50 feet (15.2 metres) long rolls. Used to wrap exhaust to retain heat in the exhaust system. Can withstand temperatures of up to 2000°F (1093°C).
The wrap is held in place with lock wire or the stainless steel tie wraps.
Using exhaust wrap can increase the performance of your engine. Wrapping the headers of your exhaust system will effectively prevent your exhaust tubes from cooling down, therefore keeping the exhaust gases of your engine at a high temperature.
Maintaining the exhaust gases at higher temperatures increases performance on several levels. For example, when travelling at higher speeds the gases will increase the scavenging effect and improve the performance of the intake and exhaust systems as a whole. The exhaust gases are therefore removed faster from your exhaust system when hot. Exhaust wrapping also expels the hot exhaust gases more quickly due to decreased density, leaving room for purer, cooler air in and around the combustion chamber. This will increase the quality of the air-fuel mixture and thus improve the engine performance.
To help with fitting exhaust wrap, you can moisten the wrap to make it more pliable (do not soak the material). Once moistened, wrap the material around selected pipe and secure in place, ideally with a stainless steel tie. Then tightly wrap the rest of the pipe, overlapping by approximately 1/4 inch (6mm) each time. Then fasten at the other end with another tie. More ties can be added to help secure in place if required. As a rough guide, 2 inch (51mm) diameter pipe will use approximately 47 inches (1200mm) of 2 inch wide wrap per foot (300mm) of pipe. Likewise, 3 inch diameter pipe will use around 59 inches (1500mm) of 2 inch wide wrap per foot of pipe.
As an extra option to finish off a clean and well-protected Exhaust Insulating Wrap application it is recommended to use the Hi-Heat Coating. The coating will protect the wrap from abrasion and harmful liquid spills. Extra resins and binders toughen the surface, extend the life of wrap by protecting it from friction, and seal the pores to minimize the penetration of harmful liquids. Using the heat coating is not essential but can prolong the life of the wrap.
Once fitted, allow the wrap to dry then start the engine in a well ventilated area. This will then let the exhaust wrap material cure. Some smoke may appear at this point. This should last no longer than 10-15 minutes. Smoke should not appear again once the wrap has fully cured.
