From what I know about exhuasts, I would think the PC and Bassani cb could be one of the deepest sounding...not the loudest, but possibly one of the deepest. I want something that not everyone has, and after having an integra...I want a deep v8 rumble.
I have place my Bassani Sound Clip on my web page it will automatically play, it however might tkae a few minutes to load depending on your connection speed. It is a 11M file. http://www.weather-check.com/bassani.htm
