I think your car will make a good guinea pig for testing these headers. The fact that you're supercharged suggests that the headers may be put through a bit more stress than in a N/A situation, which will lay a good foundation for what us N/A folks should expect.
I know that i've got your forum ID written down and will hit you up in a month or two to see how things are going with them. Like I said, if I can get SS headers for $115 then I can justify the minimal performance gains.
