Black Titanium Exhaust Wrap, with LR Technology, is made from pulverized lava rock, stranded into a fiber material then woven into a proprietary weave. Black Titanium wrap is engineered to be stronger than most wraps and more durable for improved thermal performance and reliability. Designed to be pliable and resistant to chemical oil spills and vibration breakdown; it secures tightly without pre-wetting and is able to withstand direct heat up to 1800°F and intermittent heat up to 2500°F.
