I am trying to get an idea about how loud the DB of an exhaust actually is.  
so what have your cars been tested at??

something like this  
stock vs a cat back on the market  
Idling 65 dB 76 dB  
Approach exhaust noise (4500 rpm) 86 dB 92 dB  
3000rpm 80 dB 86 dB  
5000rpm 91 dB 95 dB  
4000rpm - 6000rpm response 100 dB 108 dB

But just reading that does not really tell you how differant it is
