Lol, I want that sticker... edited for a sc of course. Where did you find that?
Oh, and my experience with the SD headers hasn't been great, its been a b1tch to stop leaks. But mostly from not clamping them right. Plan on welding in the section from the vband back to the stock flange, should be solid then. A bit of a pita yes, but I would do it again to save a lot of money that went to other things.
