HogMike, you embarrass me man, I'm strictly a Visa and cellphone kind of mechanic.
I have the fullsac cores purchased from Steve, but installed at the dealer. Using the stock muffler shells.
I was looking for good instructions to give my tech. A good guy and would do anything I asked him to do.

Reason I asked is there are a couple of things you can do. Wrapping the baffles does not seem to help.
Making sure you have good packing between the outer shell and the inner screen (about 1/2 inch) is what we see most.
You CAN have your guy check these things, and if the OEM glass is gone, replace it with about 1 inch of new long-strand glass, but, make sure its between the outer shell and the screen, you need that air gap between the core and the screen. I'm going to try some of this stuff one of these days to maybe quiet my bikes down a bit more:

Didn't mean to embarrass you, just assumed too much on my part!!!
Hope this helps a bit.
