Insulating Exhaust Wrap Part # 88-0173-1
Reduces Under-Hood Temperatures up to 70% Increases Horsepower & Fuel Efficiency Withstands Heat up to 2000 Degrees  The original Exhaust Insulating Wrap was developed over 12 years ago by Thermo-Tec. Exhaust Insulating Wrap is an innovative way to create more horsepower and reduce under-hood temperatures. Wrapping headers maintains hotter exhaust gases that exit the system faster through decreased density. Increased exhaust scavenging is produced, along with lower intake temperatures. Exhaust Insulating Wrap withstands continuous heat up to 2000°F, and contains no asbestos. Thermo-Tec exhaust wrap will not over-insulate a system when properly installed due to a proprietary coating developed by Thermo-Tec - Thermal Conduction Technology (TCT) - that conducts heat across the wrap's surface. This coating controls heat build-up and dissipation. Just wrap it around your exhaust pipe and secure with lock ties P/N 88-0174-1. Protect wrap with Hi-Heat Coating spray P/N 88-0175-1. Wrap roll is 50' x 2" & 1/16" thick, which is enough to cover one header or exhaust pipe.   Learn More
