Modifying a motorcycle's exhaust system cannot be registered. Below is relevant information about exhaust modifications: Removing the end muffler: The primary function of the end muffler is to reduce engine noise. Removing it will make the engine sound louder, but it won't affect the motorcycle's performance. Changing the exhaust pipe material: Replacing the exhaust pipe and shortening its length reduces the exhaust path, increases exhaust flow, decreases the motorcycle's weight, naturally boosts horsepower, and makes the engine sound louder. Removing the catalytic converter: The catalytic converter is a honeycomb-like structure. Removing it makes the exhaust system more efficient and the engine sound louder.
