I have a decent set of headers for a 400F sitting in my basement. $60 shipped if you want them. They aren't show condition, but they are clean enough to look good. If you are interested, then I can post some pics. I also have a Kerker 4-1 that is in near perfect condition... I'm still planning to put it on my 350F though... just wanted to brag a bit. ;-)
