I ran my 14" magnaflow dumped over the diff for a while, nice rumble, quiet in cab. Now it's dumped before axle and its drone city between 1500 and 2000 rpms.

run a 22" magnaflow dumped after the axle and run a cutout before it for when you want it loud...you can get a cutout that you have to unbolt for cheap or spend a little more and get an electric cutout

Here are some vids when my truck was just stock with the magnaflow in place of the stock muffler.

We have an 05 4.8 ecsb with a magnaflow dual exit catback and the drone down the interstate is rediculous. It still has cats and manifolds.
