High underhood temperatures are bad for performance.

That’s why Techflex has developed a line of header wrap that is good for temperatures up to 1,200 degrees F. By containing those exhaust temperatures and cooling the air in our engine compartment, TechFlex header wrap helps increase horsepower. It’s available in one- and two-inch widths and in natural and black colors.

Techflex header wrap is manufactured from texturized fiberglass yarns that are woven into a strong and flexible wrap with vermiculite coating. Remember, when installing Insultherm exhaust wrap, overlapping 1/4 in. is perfect as this allows just enough heat out to ensure performance without damaging your exhaust.
