I have a 3 inch open pipe going from the outlet of the turbo to the tail. Only a high flow racing cat is in the path.
It is really very manageable. Floating the pedal just right will let you drive past cops, even ones at random check-points out of their cars. Yet people 4 cars back can hear you take off to pass someone. And parking garages! Oh man. You can come down one engine braking at about 2.5k and EVERY alarm will go off. And people cover their ears, well, non-enthusiasts anyway.
