Superwool is a calcium-magnesium-silicate insulation material that is similar to fiberglass. Most fiberglass will melt at 700 degrees Celsius. Superwool is rated to 1300 degrees Celsius. Fiberglass also tends to shrink and become brittle at higher temperatures. Superwool is however not specifically designed for use in glass pack exhaust systems. Well, we'll see about that. I've decided to pack the exhaust can of my RC51 and see how it holds up. When working with superwool or even fiberglass it's a good idea to protect yourself from the fibers. They can scratch your eyes, and get embedded in the lining of your lungs. That can suck.
