The DEI Black Glass Fiber Exhaust Wrap (Part Number: dei10099) is designed to effectively manage under hood heat and enhance exhaust system efficiency. Wrapping headers and down pipes with this 25-foot roll of 2-inch wide heat-resistant material is a critical step toward reducing unwanted heat buildup that can rob power and compromise engine performance. This exhaust wrap helps lower under hood temperatures by an estimated 50%, leading to a cooler air charge and improved combustion efficiency. Additionally, by maintaining higher temperatures within the exhaust gases, it decreases exhaust density and promotes faster exhaust flow, contributing to increased horsepower and overall engine responsiveness.
Constructed from durable glass fiber capable of withstanding direct heat up to 1200°F and radiant heat up to 2000°F, this wrap is built for high-performance applications. Its added thermal retention properties make it a reliable choice for enthusiasts seeking to improve their vehicle's power output while effectively managing heat. The package includes stainless steel locking ties from Design Engineering, ensuring a clean, professional, and secure installation that prevents unraveling during high-temperature operation. The wrap features comprehensive installation guidelines to facilitate proper application, making it suitable for both experienced mechanics and DIY enthusiasts.
It is important to note that wrapping catalytic converters is not recommended, as excessive heat retention can reduce their lifespan. Instead, consider using DEI’s Corvette Catalytic Converter Shield or similar protective solutions. Once the exhaust wrap has been heat cycled, it should not be removed or repositioned because the fibers lose flexibility after heating, which may affect their thermal properties. Additionally, DEI advises against wrapping titanium exhaust systems, as these alloys are designed to dissipate heat efficiently and can become brittle if wrapped, risking premature cracking. For heat management on titanium exhausts, DEI recommends flexible heat shields as a safer alternative.
This versatile product is ideal for universal applications where reducing under hood temperatures and increasing exhaust flow are priorities, ultimately leading to improved horsepower and engine efficiency. With its high heat resistance, durability, and ease of installation, the DEI Black Glass Fiber Exhaust Wrap is a trusted choice for performance enthusiasts seeking optimal thermal management.
