Black Heat Insulated Wrapped Drag Pipes Exhaust Headers for Harley-Davidson FXST 1984-99

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 2000F, 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.
