The DEI Exhaust Wrap Part Number dei10121 is designed to significantly reduce underhood temperatures and enhance exhaust system efficiency. This 15-foot roll of 2-inch wide black glass fiber wrap is an essential upgrade for performance enthusiasts seeking to optimize their vehicle's thermal management. Wrapping headers and downpipes with this high-quality exhaust wrap helps decrease unwanted heat, resulting in a cooler air charge that can boost horsepower and overall engine performance. Additionally, keeping exhaust gases hotter within the exhaust system reduces exhaust density and increases flow, further improving power output. The wrap withstands temperatures up to 1200°F directly and 2000°F from radiant heat, ensuring durability even in demanding conditions.
The installation process is simplified with the included stainless steel locking ties, which provide a clean and professional appearance. This combination of materials ensures added durability and heat retention, making it a reliable choice for high-performance applications. It’s important to note that wrapping catalytic converters is not recommended, as overheating can shorten their lifespan. For protecting catalytic converters, consider using specialized shields like the Corvette Catalytic Converter Shield or Floor & Tunnel Shield II.
This exhaust wrap is not designed to be removed after heat cycling, as fibers lose flexibility once heated, though their thermal properties remain unchanged. Avoid wrapping flex-pipes or flex-joints to prevent potential damage. DEI does not recommend wrapping titanium exhaust pipes, as retaining excess heat can make the alloy brittle and prone to cracking. For titanium systems, alternative heat protection methods such as flexible shields are advised.
Whether you're looking to reduce underhood temperatures by up to 50%, decrease exhaust density, or improve horsepower, the DEI exhaust wrap provides a professional-grade solution. Its high-temperature resistance, ease of installation, and durability make it a popular choice among automotive enthusiasts aiming for peak performance and reliable heat management.
