Rush slipons & baffles?

[Semmessporty]

How long do the baffles inside Rush slipons usually last before you have to replace them? I just put some 1.75's on my 07 Sporty 883L.

The packing on the baffle may burn out after a year or two and can be repacked again,but the baffles themselves usually last for quite a while unless you do all short hops and they never heat up to dry the condensation off them.
