The minimum is still 15. There was a misunderstanding with the builder but ultimately the builder's pipe supplier is the culprit here. That being said, sfdownhill and I are taking a little break from this for the moment. Never say never but probably won't be for a while, if we do go again. This last run seemed to take forever just to get in the orders and then to get them completed seemed prolonged as well.
I'm glad to be part of it and can't thank everyone enough for being patient and even purchasing them. Also like to add a big thanks to CornerCarver, his loaning us his 2 Bros headers helped this all get off the ground.
Cheers
