Full Mac Exhaust Or Cutouts?

[MyJayy]

I was planning on buying a full mac exhaust for my 08 gt, but now I want exhaust cutouts.
Can anyone give me some advise or help me decide on what to get ?

Best advice is to listen to clips on youtube or other sites. I know that American Muscle has sound clips too. That way you can hear what they actually sound like on a Mustang and then pic the one that you like.
