We live in lower city Hamilton, not too far from the escarpment (having moved from BC, I still struggle to call it a mountain). The racket from loud exhausts going up and down the access roads is relentless on weekend evenings and nights. It's mostly what sounds like air-cooled v-twins, but some sportbikes are mixed in, revving off the redline. Even as someone who loves most motorcycles (including loud 600 i4's), I get pretty irritated, so I can only imagine how a non-rider feels. Enough irritation leads to complaints, leads to crackdowns, and then LCD rules applied to all. It's what's keeping my Tuono exhaust stock, actually, not wanting to be a hypocrite...
