I know I have had to do extensive rework of many items I have bought for the truck so far. I am just going to consider it part of the fun, rather than going crazy. I had the same problem with the fenton set, I was aghast when I received the intake in a box that had "made in china" on the side. I don't recall where the headers were made, I believe they had been repackaged. I did see a post on this forum, or maybe chevy talk, from some fella that did the importing (at least claimed he did) of these parts. And he was saying the quality was getting so poor that the people that held the license was having the patterns redone. And after the existing stock was depleted. The new revised editions will be coming out. He may have been blowing smoke as far as I know, but that was his story. (or something along those lines)
