A motorcycle exhaust baffle inserts into the exhaust system as a way to reduce noise or sometimes to alter the characteristics of the engine's performance. An exhaust baffle works by disrupting the flow of exhaust gases thereby reducing sound levels as the gases exit the motorcycle's exhaust. In addition to reducing noise, baffles can influence the backpressure in the exhaust system for optimal engine performance, as it helps with the proper expulsion of exhaust gases and intake of fresh air-fuel mixture. Baffles can also help with fine-tuning the overall exhaust system and help manufacturers comply with laws regulating motorcycle noise levels and emissions.
