Hey there Joe, sorry, I just saw this. I seem to get notifications for replies to the post but not PMs. My email is

No less, to directly answer your questions, the loudness is right around 94db when driving. My standard PSE is about 92. I don't have a good way of testing under hard acceleration but I would expect it to be linear in loudness to stock. Simply a hair louder. In my opinion, it sounds meaner and makes the car sound like a true exotic. Frankly I love it. I think it was you I told but if not, forgive me... the only reason I need to part with it is because it classes me up in autocross and in my opinion, the performance gain is not big enough for the class up and run with the heavily modified guys.
second note coming, this one is too long...
