I've fitted something similar in my new pipes, but I'm yet to decide whether I really like them or not.
As Billie I has quite rightly observed, the deeper tone of the TORS does sound better (in my opinion) but the Classics with the "Hi Level" baffles (similar to the JCs, only slightly longer I think) may turn out to be more suited to the larger capacity (904cc) and pod filters (K&Ns) of my Bonnie. I plan to take both sets of pipes to the dyno-tuning garage next week where I hope to make a comparison.
Incidentally, while Pat's no doubt right about the JCs being a universal fit, I found that I had to make my own spacers in order to achieve the "snugness" I wanted for my set. Also, having tried and rejected the white fluffy wadding in favour of purely mechanical baffling, I found that I was able to increase botom-end power by hammering a large steel washer down the inner end of each baffle. Mind you, when I told my dyno-mechanic about this over the phone he audibly winced and said not to worry as he shouldn't have too much trouble removing it when he tunes my bike next week. Oh well, so much for Heath Robinson.
:-D
