Funny you mention that. They mailed the headers to me and only took a day. I got them out to look them over and what do I see? 2 PINHOLES on one of the pipes where it turns down from the head! I'm getting a bit frustrated at this point now. I called them and they're going to make it right. Mail them back, fix the holes, and recoat. I don't even know what to say at this point. It's beyond irritating. Their customer service has been fanatic though. I will give them that.
