Well, I definately don't have a source for the Amuse #s but I was just trying to say that the full exhaust system would probably be louder than a Eisemann race (which is abt 102 db). I just threw a random # out there just to make my point that the Amuse would probably be louder than the RACE considering its a full-exhaust system. The #s are greatly affected by where the sound is measured, and I suppose that Eisemann did not measure this 102db from the cabin and windows up. Therefore, being a sports/luxury car, the "110db" from outside would definately not translate to such a high level inside the cabin.

I don't know what the #s for the Kreissig exhausts are, but I can tell you with a straight face that those probably do over 110+db (measured from outside)

And btw, the threshold of pain is 130db (

Lastly, if you are judging an exhaust's volume based on youtube videos, I can tell you first-hand those videos don't do any justice. Even when Nate from IND posted high quality vids for the Eisenmann Race, the thing still sounded much louder in real life.
