New order will be placed this week.
Droning is not a function of the headers as such, if you fit them to an otherwise stock OEM system, there is zero drone and zero noise increase at the rear of the vehicle.
Drone is a exhaust system design function, get some good muffling in right up the front and then you are 90% on top of drone, and then of course use another muffler or 2 as needed mid to rear of mid section.
Really, for best guide, follow the original OEM placement of the individual parts and simply improve with higher flow parts/joints. That way you will likely never experience drone.
