Box opened for inspection. The flanges on the headers were rusted from the shitty silver paint. There was rust on the welds in the pipes. The tubes were 1.5 inch ID, not 1.625 inch. I believe they weren't stainless steel, or at least not 304 SS. Nowhere on the box did it say "stainless steel" except for a small sticker that was added to the box. The seller charged me a 25% restocking fee and helped with the bot.
