I'm not sure how to upload a sound file onto VCA? I can record one with my video cam and e-mail it too you? My best description/comparison would be this. I have two 18" Velodyne subs in my home theatre that when playing can really give some high SPL (sound pressure levels) at low frequency & at idle the low rumble the car has now is very low and comparable(
im a sound freak too ). My guess is it's in the 60-90hz range wich is a very nice very deep sound. When you give it some gas it realy opens up with a nice aggressive race sound but not too loud until over 3500rpm. I personally love the popping and spitting it does on the overrun. There is way way more of that

It's great to hear when your slowing down for a stop light. It finally sounds like there is a V-10 under the hood. If you want a sound I will put it toether and e-mail it to you. Just PM me
