haha good one - expecting a pig in the poke to fit all the variations that occur in Cdo assembly. What fits nice and close and clear on my Combat may not on your 850. My best suggestion is make sure of the return policy. The worse reports of past header make finish and fit, including my own, were from the most highly priced and prized heavy duty Victory pipes, so I can't recommend theirs going by my having to grind for header end and ring nut almost to destruction to fit when my factory headers fractured. Yet others this last decade are pleased to hi heavens by Victory so let us know what works for yours.
