Says with Sport off it's not much different to the OE exhaust in Sport mode, but with Sport on it sounds like a "proper" V8.
Once I've saved my pennies I reckon I'm going to go the non-res/valved route - then I can drive with Sport off when the wife is with me (I always drive with Sport on at the moment), and have Sport on at other times!
That would be me. Go non res/Valved if you want the best of both worlds. Stock "S" mode sound when you have S mode OFF (slightly louders at startup, but NO drone), and great sound with S mode enabled. I only get drone when in 4th, 5th, or 6th when it's lumbering around 2-3 K on the tach. Highway speeds, even in S mode, there is no drone at all, and I love it. If you want to kill some of the drone at 35-45MPH, then just turn S mode off and it instantly disappears. I'm rarely in drone territory but a few seconds, but I've tested it. Amazing what the muffler flaps will do. You gotta remember, this system opens/closes the flaps depending on RPM, so it's still very tame. It's pricey, but I'm glad I did the valved. You'll crap an egg on a cold startup. It sounds amazing.
Hope this helps,
