The neighbor down the street has a loud ass exhaust on his Yami. He starts it up @ 5:30 in the morning with the garage open (echo effect), idles and revs it too much. His neighbors had enough, called the HOA and made a formal complaint. He went back to his stock muffler. I honestly believe the police would have been called next.
Being heard ain't always a good thing. Especially in the wrong setting.
