I live in a high-rise apartment, but not high enough. My windows face the street.
People ride loud motorcycles down the street at night. Late night - almost morning. My baby does not like it.
Since all other motorcycle manufacturers know about mufflers, I assume that they are Harley-Davidson motorcycles. They have "mufflers" that consist of a straight metal tube covered in chrome. It moves the exhaust gasses from front of the rider to behind the rider.
If the Harley-Davidson muffler directed the noise from the exhaust manifold to the vicinity of the rider's ear, then I would respect them for what they are doing. I do not respect those that make noise that they are not subject to. If there was a Harley-Davidson in the forest, and no one around but the rider, I couldn't care less. As it is now, it's the Harley-Davidson-exhaust-noise-tree falling in the forest on top of me, my baby, and everyone trying to sleep for two city blocks around. If those riders are doing it on purpose, they are sick motherfuckers.
