  • 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.

  • 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:
    • Superior Abrasion Protection Built To Handle Extreme Off-Road Use
    • Dual-Layer Design/Hi-Temp Fiberglass With 304 Stainless Steel
    • Interlocking Mesh Makes Installation Much Easier
    • Pre-Wetting Roll Not Necessary For Wrapping
  • EXO Series exhaust wrap solves the problem of extreme exhaust heat in extreme environments like offroading and powersports. EXO Series exhaust wrap is designed for extreme environment use. Traditional exhaust wraps have not been able to withstand the extreme use that Off-road, Dirt track, Desert and other forms of driving have with exposure to water and dirt. The EXO Series is a dual-layer design, using a combination of hi-temp glass fiber, covered with a 304 grade stainless steel exoskeleton. This unique construction maintains high heat protection while offering superior abrasion and impact protection. Our unique Air Gap Technology keeps direct contact of the glass fiber wrap off the hot surface creating an insulating air barrier. The EXO Series exhaust wrap comes in a special 1.5 in. width, making it easy to install on any type of header, exhaust pipe or exhaust system making it perfect for high impact spot protection. In addition, the stainless steel exoskeleton locks together when overlapped keeping the wrap tight and making installation easy. Delivering outstanding looks and Rugged performance for long term durability, available in Black or Tan in either 1.5 in. x 10ft, 20ft, or 30ft rolls. 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.

  • DEI's ORIGINAL Titanium(TM) exhaust wrap, with LR Technology, is made from pulverized lava rock, stranded into a fiber material and woven into a proprietary weave. Titanium wrap is engineered to be stronger than most wraps and more durable for improved thermal performance and reliability. Perfect for any automotive or motorcycle application! Withstands 1800°F direct/2500°F intermittent heat Promotes increased flow for improved performance Reduces temperature & vibration breakdown Extremely pliable for a tight and secure wrap DEI HT Silicone Coating not required Pre-wetting roll not necessary for wrapping Hi-tech carbon fiber look High resistance to abrasions, oil spills, temperatures and vibration breakdown 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. 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.
