Glass Fiber Exhaust Wraps solve the problem of extreme underhood heat and improve exhaust system performance. Wrapping headers and down pipes is an important first step in reducing unwanted and power-robbing under hood heat. Less under hood heat results in a cooler air charge 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. Reduce under hood temperatures a realistic 50% Decreases exhaust density & increases exhaust flow Improves horsepower Withstands 1200F direct/2000F radiant Only exhaust wrap with installation guide lines Added durability and heat retention 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. Titanium Exhaust Pipe Systems: DEI does NOT recommend wrapping exhausts made of titanium. The alloys used in the production of titanium exhaust systems tend to be thin and are designed to dissipate heat quickly. Wrapping any titanium exhaust pipe, regardless of brand, can hold in too much heat, and make the titanium alloy turn brittle and prone to premature cracking. If you are seeking to reduce the heat on a titanium exhaust system, DEI recommends using alternatives such as our flexible heat shields.
