NE1 have experience with FMF's quiet core insert ?

[JerseyDirt]

I have the Powercore 4 s/a and it's loud as a mofo. I like it when I ride closed course, but would like to be more respectful in the woods. Has anyone tried the FMF modular quiet core insert in the Powercore4 muffler and if so, what were your impressions?

Thanks,

JD ?

I use one with my PC4 on my DRZ when running ds events or riding near houses. It does decrease the sound a bit. I did notice a bit of a loss of top-end... no big deal when riding tight woods.

I've been sound tested twice with dramatically different results. The first time I blew 95db. The next time I was tested I blew 101, but I think their standards were off and they also had me revving the motor very high.

Thanks. Just to clarify, are you using this one?
