Flowmasters and other chambered mufflers are known to drone a lot more than straight-through designs like magnaflow, Borla, etc, especially a single chambered 10 series. I think the 5.0 with magnapack will be a nice combination and on the highway will only drone under load (like towing or going uphill).
