Ain't strictly comparing apples, but I put a Fullsac pipe on my '12 103 along with their 2" re-core kit and with a set of 255 cams. The left-side non-CVO muffler re-core has a forward stand-off ring just like the rear ring (though without the threaded holes), so I could not leave the stock "packing" screen in place like I did on the right side. I ended up having to disassemble said "packing" and re-assembled it between the stand-off rings. That got rid of the slight amount of resonant obnoxiousness that was emanating from the left side muffler.
The overall sound is definitely louder than with just 2" core slip-ons on the stock cat headpipe (and stock cams). It's (now) a sweet sound, though, and does not interfere with tune appreciation in any way. From what I know of the CFR cans, I'd have to say all else being equal (it's not) you'll end up a bid louder than I am. So I guess that in the end, I've just wasted both our time... :-) Though if you know firsthand the difference in sound quality between your bike and a 103 with the full Fullsac exhaust, and the difference between the Fullsac re-core mufflers and the CFRs, you might have a little bit to go on with what I brought to the table.
