Well, I think its a sin to muffle V-twins - except Harleys. The afterfire only emulates Ducati singles which had the Brevetti "Silentium" mufflers and Del'lorto carbys. "I" would have chosen different cans myself. Re-pop Dunstall "Decibel Silencers" would certainly fit the café theme. Still loud, but less obnoxious. The Euro CXs had a better frame, but I see he used the Yank style. Still, it came out far better than most of the flat seat, monster front tire hack-jobs I see. And the CX650 has some real steam. Not as quick as a V11, but not far behind, either.
