Muffler/Exhaust

I am considering buying a Gibson import muffler OR Gibson Exhaust system for my 2002 Maxima (auto). I heard that it adds a nice deep, throaty sound to it, not like those 4 banger rice burners that you see all the time. Does anybody have any advice or opinions about this?

Thanks!!

Gibson ?
WTF is that ??

:confused:

I'm getting the Gibson cat-back muffler for my Xterra, I've heard good things about using it with an K&N air-charger for intake. The sound should be deep, but not loud and annoying like the rice burners.
