How does it work? "One thing that is commonly overlooked by most racers is the matter of heat retention in the exhaust pipes. We have to remember that as soon as the combusted gases leave the chamber, they start to cool down. As they cool, they loose velocity, and the scavenging effect is reduced. If the temperature of the gases inside the pipes is kept as high as possible, the net effect will be greater velocity, greater pressure drop in the system and higher efficiency.
2" Exhaust Insulating Wrap

Very recently we have experimented with heat-retention materials to improve the efficiency of exhaust systems. These shields retain heat in the exhaust pipes, so the exhaust velocity remains very high. This will improve the scavenging effect"
