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. Like the original Titanium Wrap, DEI's Black Titanium Wrap maximizes horsepower and performance by reducing underhood temperatures and maintaining high exhaust gas velocity. Wrapped headers and exhaust also reduces the incidence of heat soak, can prevent harmful burns, protect heat sensitive underhood components, and reduce the level of heat transmitted through the firewall and floor of the vehicle for a more comfortable interior. Black carbon fiber look Extremely pliable for a tight & secure wrap Withstands 1800?F direct / 2500?F intermittent heat Pre-wetting roll not necessary for wrapping Reduce underhood temps NOTE: Catalytic Convertors: Wrapping of the catalytic converter is not recommended, as overheating can lead to reduced lifetime of the converter. Instead, try our Corvette Catalytic Converter Shield or create your own shield using our Floor & Tunnel Shield II(TM). Removal: Exhaust wrap is not designed to be moved or removed after it has been heat cycled. After the fibers have been heated, they lose their initial flexibility. This does not reduce the thermal properties of the exhaust wrap. Be aware of this before you decide to remove the wrap. For this reason, you should avoid wrapping any flex-pipes or flex-joints.
