RK4ever, I have the V&H basic slipons on my 01 RK. Wanting more noise, I pulled the baffles and cut 3 inches off the length and reinstalled. Nice sound, but riding partners didn't want to ride behind me due to the loudness. The loudness induced headaches and ear ringing. Bought new baffles and packing. This time I'm leaving them alone.
Or, if you like the sound it presently makes, pull the baffle out and smack the inside of the inner 'cup' with a ball peen hammer to make the diameter a little larger. Not too hard tho, it still has to fit inside the muffler. You could also shim the inner 'cup' to keep it from vibrating. The packing is probably pretty much gone.
If you want it a little more quiet, you can repack the baffle with new material making sure there is enough to keep the baffle itself from vibrating, or replace it with new if you like throwing money away...
