I had a set of cored factory touring mufflers that were leftover from the RK. I took them off the RK when I added the DCC fairing cause I couldnt hear the radio. They sounded good at cruise and had alot of bark when on the throttle, but when I was above 3000 rpm the radio went away.

On the EGC, a cali 09 cat headpipe bike, the bark is gone as far as I can tell. Still crappy weather up here, so I didnt get any real seat time. They are louder, but REALLY muted as compaired to the RK. I will know more tomorrow after a trip to work and back on her. I may need to change the headpipe system to get any REAL sound out of her, or it may be just enough.
