I think looking on youtube is a waste of time. A recording device, unless it very very good, won't give you a true indication of the sound of an exhaust. Also your relying on it being uploaded perfectly, it not using a bad compression, and your speakers being capable of a perfect playing of the track.

Go around to a few exhaust shops and see if they have any being worked on.

I prefer the sound of a single 3inch
I've got pacemaker extractors, y-pipe that joins to a single 3 inch just behind the gearbox, a 3 inch turbo muffler and resonator. It has a nice deep note at idle and low revs, and doesn't bark or drone at all.

as mentioned, it is a bit difficult to get an accurate indication of the sound from a recording, but here's some video camera footage of my VH at Lakeside. Might give you a bit of an idea

VT SS 5.0L
I've currently got a single 3 Inch cat back in my VT at the moment, its ok but i think unless you do a full system 2.5inch is the way to go. My friend has a 5.0L with a twin 2.5 and in my opinion he's sounds alot better then mine. He also invested in some high flow cats which seemed to give it a nicer note.

5.0L VS EXECUTIVE
I didn't want an offensively loud system when i had my 5L so i went with a 2.5" single mandrel bent cat back with a high flow cat, nice and quiet when i wanted it to be but when i jumped on the loud pedal you certainly knew it was a v8.

Its havdy to be able to have a stealthy exhaust cause i was able to keep it quiet when the filth was around and never had any dramas with them.
