does the HFC your lookin at have any resonators on it?? if not it might not be quieter bc the Dinan has two resonators on it. as you can see it is only loud when getting on it. i should of have done some outside where it is just cruising by
i never noticed any at that rpm range up hill but there is a long few miles stretch of highway that is a steep grade up a mountain so i can take one on that this week for you and run it in that range up the hill and see if it is any different
i need to get a real video camcorder bc the camera one with video feature has poor quality
will post it soon as i get it done

I can't exactly tell 100% from the videos, but is there ANY resonance (hum/sound vibration) at 2900-3200 rpm going up a hill in 6th?
