theyre supposedly obx knockoffs, some people have no problems, some people have bad welds, its pretty much a gamble. depends if your ok with running a cracked header until you can go to a shop to get it rewelded
how much you want for it?
+1 and the sellers usually will usually give you a hard time if you want to return the item... and they dont speak english very well... you may want to go with brand name header just to be on the safe side
