Dads50, I don’t think I have an exhaust leak, but I would not be surprised if there is something small. I do not have a sandblaster, so I may be taking it to a shop and hopefully they can check it carefully for cracks or other issues. When you say decked, is that to align the ports into the same plane and flatten the faces?
