nice job man, i have the same header and thought about doing the same.. but it looked so purdy shiny i just left it as is. lol

 

What does the silicone header spray do?

 

The silicone spray serves 2 purposes. It acts just like any radiator spray you can get in that it helps dissapate heat, and it protects the header wrap from dirt and debris. If it does get dirty and i can wipe it down with a damp towel and recoat it.
