I received mine the day I left for the Nat's and just had a chance to unpack and take a look yesterday. Was a bit worried as they were packed in a regular header sized box and loose inside, but thankfully they were adequately wrapped with lots of bubble wrap so no damage during shipping. Overall, I would say, I'm not overly impressed with the overall quality, the welds could definitely be prettier. They look like normal production MIG welds, no nice stacked dimes look on these welds. I didn't notice any loose slag, or anything else on the inside. The pipes could have been fit and trimmed a bit better internally in my opinion. Not sure how the coating will hold up long term, the inside appears to be coated only near the openings like over spray. Before I install them I might send them out for Jet Hot or other coating. I was disappointed when they originally advertised they would be made from stainless and then changed to mild steel. I don't know when or if I'll get them installed on the car so I can't give any feedback on fit or how they work. Of course in the latest GSExtra, they talk about how great they fit and work, so we'll see. Supposedly several sets were made before full production and changed were made due to feedback, so hopefully these will be trouble free.
