Although I'm positive the video is jacking up the sound a bit, that sounds a little sickly for a 3.0L V6, more akin to what I'd expect from a Zetec....
From my personal experiences, Magnaflow+smallish displacement engines= bad sound quality. They genuinely sound better on V8's and such.
If I had a 3.0L Ford V6, I'd be looking more at Borla S-types(stingers) in the stock positions, with maybe two round resonators after the X or H, whichever you happen to have on your duals.
But that all depends on the kind of sound you are looking for....
You might look into Spintech Sportsman mufflers...they have a certain exotic tone to them that befits DOHC sixes like yours....
