I run a stock exhaust and an AirRaid CAI. I think my car sounds great.
I also had an old 73, with a 351C. That was a good sounding car. This new 13 V6 may not sound quite as good, but would stomp the guts out of that 73 in every other category.
Recently I heard a 5.0 that I thought sounded, lets just say, not so good. It was loud, but there's a difference between loud and good, in my ears.
