High density fiberglass muffler re-pack. Tight weave high density packing is preferred by 4 stroke riders to control sound & backpressure.
Can be applied to muffler core in layers that allow for fine tuning of backpressure that effects the torque curve to achieve desired feel & performance.
For street or off-road machines.
