DEI 10102 Exhaust Heat Wrap 2" x 50' Roll - Tan

The Design Engineering DEI 10102 Exhaust Heat Wrap is a high-performance thermal barrier designed to reduce under-hood temperatures and improve exhaust system efficiency. This tan-colored wrap measures 2 inches wide by 50 feet long, providing enough material to wrap headers, exhaust manifolds, downpipes, and other exhaust components on most vehicles.

Key Features:

• Reduces radiant heat damage and decreases under-hood temperatures by up to 50%
• Increases exhaust scavenging to improve horsepower and performance
• Keeps heat inside the exhaust tubing for faster exhaust gas velocity
• Withstands continuous temperatures up to 1200°F and intermittent temperatures up to 2000°F
• Tan fiberglass construction with a natural, classic appearance
• 2-inch width is ideal for wrapping motorcycle pipes, car headers, and turbos
• 50-foot length provides coverage for most exhaust systems

Exhaust heat wrap works by insulating exhaust pipes, keeping heat contained within the system rather than radiating into the engine bay. This reduces ambient temperatures around sensitive components like starter motors, fuel lines, and wiring. The improved heat retention also maintains higher exhaust gas temperatures, which increases flow velocity and can improve turbo spool time and overall engine performance. Professional installation is recommended, and DEI's HT Silicone Coating (sold separately) can be applied after installation to protect the wrap from moisture and abrasion.
