I've heard the quite system on a stock SVT and at idle, it's quite similar to the stock sound. As you get on the gas, the sound becomes louder and pleasing. I would, personally, describe it as inbetween a Borla (sounded like stock to me when I drove the car) and a Bassani with res's in (a bit too loud for me). For those that want this in-between sound, it's just right. Personally, it's the nicest sounding exhaust I've heard out of stock, Borla, & Bassani so far, although I haven't heard the loud system yet. The quite system had no res in it for optimal flow and take my word here, there was no rasp at all like you'd get if you pulled the stock res out and put straight pipe in.
