If you notice in my pics, they headers are black. I used high temp header paint. The set shown is new, the set on my 00 SVT has been on for almost 12000 miles and they look the exact same way (car is not driven in winter though) If you are worried about rust, paint them. I think MSDS frowns on it, but what can possibly break to require warranty work (assuming you inspect the welds first) And beleive me you do not want to have to unistall them, once they are in, they are in.
As for using a Turbo with them, unless you have the means of making your own downpipe etc, stick with the complete turbo kit.
