Design Engineering Inc. Black Titanium Exhaust Wrap Titanium exhaust wrap, with LR Technology, is made from pulverized lava rock and stranded into a fiber material and woven into a proprietary weave. Engineered to be stronger than most wraps and more durable for improved thermal performance and reliability. Wrapping headers and down pipes with Design Engineering Exhaust Wrap is an excellent way to reduce the under hood heat that robs power. Reducing the heat under the hood provides cooler air change for improved performance and keeping exhaust gases hotter within the exhaust system helps in decreasing exhaust density & increases exhaust flow. Design Engineering Stainless Steel Locking Ties are the perfect way to fasten exhaust wrap for a easy, clean and professional installation (ties sold separately). Protect yourself and other sensitive underhood components! Features: Black carbon fiber look Extremely pliable for a tight & secure wrap Withstands 1800F direct / 2500F intermittent heat Pre-wetting roll not necessary for wrapping Reduce underhood temps
