I got one of the very first ZHP's and scooped up one of the last NA I-6's. They are not raspy and sound awesome (the 328 is too quiet, but not raspy). The E36 M3 did not sound raspy either. If you like it, go nuts.
My first car was a very used 190E 2.6 with an I-6, and that thing was smooth as silk all the way to redline (I know, I bet that was the only MB revved to redline). So I-6's do not have to be raspy.
