as for v8s from other brands, the old generation (2010) toyota tundra 4.6 lexus v8 sounded GOOD. (With level 3 magnaflows and no crossover.) super smooth anywhere under 2000rpm, nice mellow idle, but when you romped on the thing, it sounded like a damn corvette. (i will try and find a video.)
This is not exactly the same, the exhaust shop did something different to make it less, grumbly and harsh, but basically the same.
