Eliminating exhaust drone and “rasp” on a 2018 Sierra Silverado L8300:00

Adding a Jones Exhaust MF2469 muffler in an attempt to minimize drone and “rasp” from my Speed Engineering dual kit. Eliminated 100% of the rasp, but seems to have just moved the drone to another rpm range. Boost pressure remained the same, so we can assume not restriction was added.
