Hi there, I'm new here and recently read and commented on a similar thread. Starting this up here in hopes to capture anyone's thoughts on the following:

I'm having a drone issue with my 2021 Laramie 5.7 HEMI e-torque between 1500 and 2000 (i'm rounding up). Based on all the research i've done in the past week or so, I really do believe the drone issue is very common on our trucks.

That being said, my exhaust journey began two weeks ago when I decided to go with with true duals 2.5 inch w/ H pipe. The result was an awful drone! Prior to true dual I had done a simple muffler and resonator delete and left the stock 2.25 inch pipe - nice growl with no drone. I highly recommend it.

In a span of two weeks I installed a Flowmaster 50 HD, swapped that out for a Magnaflow glasspack ( i forget the part #). Although the drone is less with the Magnaflow, drone still present at 3rd+ gear and around that 1500k'ish - 2000k band.

I'll be installing a few Vibrant Ultra Quiet Resonators and giving the J-pipe a shot. Would anyone here recommend I install the longest possible j-pipe that i can fit?

Thanks!
