Need muffler recommendations?

[howzitbra]

I have a 07 OBS GMC Sierra 4.8 motor and I'm wanting to replace the factory muffler with a aftermarket muffler. The factory muffler is a single in single out. Want something with a nice sound but don't want the droning noise in the cab. Not really interested in true duals at this point in time. Any suggestions would be greatly appreciated. Thanks TBHers

It is a crew cab by the way.

Magnaflow..deep smooth sound not as (droning) as flowmaster,i love flows but sounds like your wanting mellow

i have a 2 chamber flowmaster on my 4.8 but if you dont want something super load try a 3 chamber flow and have if dumped at the back tires.
