DEI Titanium Exhaust Wrap with LR Technology

DEI titanium exhaust wrap with LR technology is constructed from pulverized lava rock, extruded into fibers, and then woven into a tight weave, giving it titanium-like strength and toughness. The improvement in thermal protection helps to reduce underhood temperatures, resulting in cooler air intake for improved performance. And less heat in the engine bay means less chance of heat soak conditions on vital underhood components. Typical glass fiber wrap is rated at handling 1,200 degrees F of maximum direct heat, while DEI's titanium wrap, using LR technology, is capable of handling direct continuous heat up to 1,800 degrees F and radiant heat up to 2,800 degrees F. And because it's pliable, there's no need to wet the wrap when wrapping headers or pipes, as many do in order to make the wrapping process easier to manage and to get a tight wrap. Titanium wrap will not shrink, and because of its material structure, it is more resistant to temperature and vibration breakdown, abrasions, chemical and hot oil spills than glass fiber wrap. Plus, DEI titanium wrap offers a very cool carbon fiber look as an added feature!

DEI Titanium Pipe Shield with LR Technology

Extreme heat can rob power and potentially damage engines, transmissions, hoses, and sensitive electrical components. DEI has introduced a revolutionary advancement in Titanium pipe shield with LR technology that greatly outperforms Mylar-backed glass fiber shields. This exhaust wrap combines the high-heat tolerance of DEI's proprietary LR fiber technology with a unique rivet-based clamp shield design to improve heat dissipation and cooling. Glass fiber shields can begin to fail at 900 degrees F, with the Mylar outer material cracking and flaking off. DEI's titanium pipe shield provides heat protection up to 1,350 degrees F. LR fiber is a two-ply material. The outer layer is made from lava rock pulverized and stranded into a proprietary, tightly woven weave for durability and strength. The inside material is made of a special high temperature-resistant fabric (89 percent silica) designed to withstand 350 degrees more heat than glass fiber. This proprietary fiber technology, combined with DEI's unique shield standoff bracket design, provides an air gap between the shield and pipe that maximizes the potential for cooling and heat dissipation. With the strategic placement of DEI titanium exhaust wrap near transmissions, brake lines, floorboards, body panels, diesel exhaust stacks, or motorcycle pipes, radiant heat can be controlled for maximum protection and performance.
