I was in such a rush to put my HFC on my 07 I did not get to scope the stock HR headers. I will pull one off and take some pics soon. Until then I can not comment on how good or bad they are.
My best 05 1/4 mile time was after my header install. It dropped my trap time by .2 and my MPH gained 3 mph. So I was happy.

I was wondering the same thing regarding the HR headers. I wonder how sloppy the internal welds and construction is? It was a popular mod on the celi's to clean up all the welds and do basic port job on the oem headers at the flange, collector, and merge. I will be installing my testpipes and exhaust this weekend, I will look at the header on the inside of the collector and report what I find.....
