A muffler is what deadens the sound that is coming out of the engine through the exhaust. Motorcycle mufflers are much smaller, usually no longer than several inches long. That is the biggest reason why motorcycles can be a lot louder than other vehicles. Motorcycles just don’t have the room for a bigger muffler.
Why do motorcycles sound so loud?
