I saw these today on ebay as well. From what I can find out about them, is they may be a re-branded OBX header. When I saw the add on ebay, I mistook them for OBX. When I came here to search, I saw your post and had to take a second look at the ebay add. If they truly are OBX-rebrand I would and will purchase. The internet is filled with good and bad reviews on the OBX brand. My personal experience with OBX is on my 98 Camaro. I've had them for 4 years with no issue of cracked welds, (the car is lowered and bottoms out on every speed bump). They still look great (stainless has that cool bluing. Installation fitment did need some massaging. Yes OBX are Chinese made and most likely so are these. I will be trying these out for the price.
