Great work. Those stainless headers do look a little disappointing, especially the spatter. I note you are looking to use a breathing set up similar to mine. I have tried two different headers similar to yours and both give a nasty hesitation at around 8-9k rpm with steady throttle. I know the power is ok and the jetting is giving good dyno curves. My bike will power through the hesitation band on full throttle without any problem, so I am thinking the issue is something to do with exhaust gas flow. The stainless headers I am using, like yours lack the internal sleeves and the link pipes, This may be significant. I shall be interested to hear how you get on.
