Motorcycle baffles are metal tubes that contain many perforations and are 2-4mm smaller in diameter than the exhaust pipe. The baffle is inserted into the muffler tube, also known as the exhaust. The perforations slow the airflow of the engine’s expelled gases, resulting in added back-pressure and noise reduction.
What do baffles do for motorcycle exhaust?
Motorcycle baffles AKA exhaust baffles are specially designed tubes – inserted into a motorcycle’s exhaust to quiet down the engine sound. Engine sound (any sound really) travels in waves. The walls surrounding a baffle tube are made to bounce sound waves – causing them to reverse, crash into each other and cancel out.
