Good "civil" sound

Great exhaust. Love the sound. Lots of gurgles between first and third. It's not loud enough that I feel I'll get a noise complaint but just enough rumble to be able to feel good about it. Drones a little around 1800 and 3100 ish but you can still talk over it very easily. overall, very satisfied.
