  • Exhaust Wrap
  • Exhaust Wrap; 1 ft. x 50 ft.;
  • Product Attributes:
    • WARNING CA Proposition 65: Yes
    • WARNING CA Proposition 65 Message: Warning: This Product Contains A Chemical Known To The State Of California To Cause Cancer And/or Birth Defects Or Other Reproductive Harm. Www.p65warnings.ca.gov
  • Features:
    • Reduce Under Hood Temperatures a Realistic 50 Percent
    • Decreases Exhaust Density And Increases Exhaust Flow
    • Improves Horsepower
    • Withstands 1200 Degrees F Direct/2000 Degrees F Radiant
    • Added Durability And Heat Retention
    • Only Exhaust Wrap With Installation Guide Lines
  • Glass Fiber Exhaust Wraps solve the problem of extreme underhood heat and improve exhaust system performance. An important first step in reducing unwanted and power-robbing under hood heat is wrapping headers and down pipes. Less under hood radiant 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 1200°F direct/2000°F radiant Only exhaust wrap with installation guide lines Added durability and heat retention NOTE: Design Engineering HT Silicone Coating spray is highly recommended for DEI glass fiber wrap to penetrate, seal, protect and prolong the lifespan of exhaust wrap. NOTE: 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). Note of Caution: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.

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. Note about Titanium Exhaust 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.

  • Features:
    • Extremely Pliable For A Tight And Secure Wrap
    • Less Irritating To Skin
    • Pre-Wetting Roll Not Necessary For Wrapping
    • Withstand More Temperature Than Fiberglass Wraps
    • Black Carbon Fiber Look
    • Reduce Underhood Temps
    • Made in USA
  • 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.
