Best Answer: Motorcycles are generally louder because of the length of the exhaust system, comparatively to an automobile. The shorter you go, the louder you get.
Although it may look like a smaller version of a muffler, resonators are designed to be supplemented into an exhaust system to further tune the sound and not replace a muffler completely. A resonator further dampens the sound but more importantly, it is there to alleviate what is known as âexhaust droneâ. Usually during cruising speeds, some exhaust set-ups may exhibit a background buzz that may be heard even inside the passenger compartment.
