Wow, just saw this for the very first time (haven't been on the forums much at all in the past two years or so). Great work!
If you need video of exhaust sound for Supersprint Race (Sport predecessor), here's one of my car @ the dyno a couple years ago, after I got supercharger put on.
And this one is of a dyno later on, after I got it retuned. Same exhaust setup.
