Off-road systems should be topped up every 6-8 hours of use, or after every race. Refilling your muffler as often as suggested is essential for your exhaust to perform the way it was designed. A dirty filler obstructs the airflow of the engine, causing loss of power and sound degradation. Changing the muffler filler frees up airflow from the engine, thus recovering lost power and improving the sound of the exhaust.
