Cool-It Insulating Car/Bike Exhaust Heat Wrap Graphite 1 Inch Wide 15 Feet Roll

By wrapping your headers with Exhaust Insulating Wrap you can maintain hotter exhaust gasses, which will exit the system faster as they are not as dense. As the gases exit the exhaust quicker, exhaust scavenging is improved, which in turn leads to lower intake temperatures.
