Exhaust Sound Clips!!! HELP!!!

hey

i need help finding exhausts sound clips for my SR20DET...please no Ka's...only turbo exhausts...
i have been looking mostly for these sound clips:
HKS Hi Power
HKS dragger 2
Greddy PE2
Apexi N1 and N1 dual

i would like to hear them from the outside of the car if possible...or maybe even just a description of how it sounds...
