Off-road systems should be refilled every 6-8 hours of use, or after of each race. Refilling your muffler at the suggested frequency is essential to keeping your exhaust working the way it was designed. A dirty filler obstructs the engine's air flow, causing a loss of power and a degradation of sound. Changing the muffler filling frees the engine's air flow, thus recovering lost power and improving the exhaust sound.
