Product Details

Insultherm Header Wrap is an extremely high temperature resistant wrap commonly used to contain and manage hot gases in automotive and high performance headers and exhausts. 

Header Wrap is manufactured from texturized fiberglass yarns that are woven into a strong and flexible wrap with vermiculite coating.

Remember when it comes to exhaust wrap, overlapping 1/4” is perfect as this allows just enough heat out to ensure performance without damaging your exhaust

Installation Process

Before installing Header Wrap, soak the entire length of material in water until it's fully saturated. Wrap the wet material around your pipes, remembering to overlap the edges slighty for full coverage. At the ends, secure the wrap with stainless steel cable ties. When your pipes warm up, the moisture will evaporate and the wrap will shrink slightly to form a tight protective seal arount the entire assembly.
