We have just had a superb replica CL250SC silencer made in stainless by Alldens Exhausts - if anyone else wants one, he isn't going to keep the jig forever, so it would be worth getting one made now! Ours is pretty thrappy as we asked for it that way, I'm sure road legal versions would be available. Not cheap at £275, but thick grade, well made stainless steel - not your quick rot cr*p, polished, looks exactly like the original, proper workmanship in evidence.

No connection other than as a satisfied happy customer - ask for Mike, nice guy.
