From what I've heard, most of the stainless products like the OBX are coming from China...and there are various grades of 304 stainless...and I have doubts as to whether some of these advertised as 321 are really 321. I'm not saying that the Chinese manufactured headers are inferior....it's just that there's no emipirical data available...no quality control info...all too new and not enough folks who have been there done that to give us some feedback. $400 for a set of headers is tempting...but not without some testing or personal experience. I'm skeptical from the standpoint of material, quality of welds, and particular composition of the stainless steel being used.
