exactly what you are wanting to know. You can get a pretty decent if not good idea of which brands to go with, resonated or not. Also 3ZC has a sticky thread with a number of audio clips of many exhaust setups compiled. Though I personally dont think you can get a true feel for what the sound/noise level of an exhaust is going to be thru a recording, especially cabin resonance.
