I'm in the same boat, I have the 3.21 gears, Carven progressive bolt on, otherwise stock. The drone and resonance in the 1500-2000rpm range is horrible. It's like the whole exhaust system is a tuning fork.I’m curious how this would be for drone in the 8-speed 4th Gen with 3.92 gears. Flowmaster 50HD is supposed to be hardly any drone and I get drone still as it cruises at hwy speed (105-112 km/hr up here) at around 1800-1900rpm which is RIGHT in the area drone happens most. A lot of performance exhaust companies show demos of their exhaust systems on trucks with 3.21 amd 3.55 gearing, 6 speed, where hwy speeds are running at around 1500rpm, just before drone starts happening noticeably.
