That sign is right in the back of my yard. My neighbour has it there now that he is retired, or close to it, he is home a lot more and it bugs the hell out of him. I'm a bit further from the hydro line than him but I do here the cans when I'm outside. Some will smash it going right past that sign. There a lot of real ignorant people out there. I have a tune on my 9000 but with the stock exhaust for this very reason. No extra noise with it at all. Its about as high as you can go without playing with the exhaust.
