I tried Bassani axle backs and now have Borla S on my 2012 V6. You'll get more people seeing the thread if you use the 2011+ V6 forum, though. Personally, I liked the bassani, lower growl , but they definitely have an interior drone. My wife couldn't stand it, so now I just found some used Borla- S axle backs, and am trying to sell the bassanis. The Borlas have a higher pitch, but no drone. Like everyone says, you won't get a V8 sound. Funny, though because I hear some pontiac V6's with a low sound. Wonder how GM did it? I am getting shorty headers, so I can keep the stock catalytic converters, and I hope the sound gets a little lower and meaner.
