I am looking for an original R400 silencer for my 2005 SLR 400!
might be worth a call to Chesman if your looking for the OE version made for CC.
If not I can recommend Mike Edwards 07742 475 953 - whatsapp or face book him here:
Superb workmanship and a very helpful guy too.
For a newbie among the abbreviations you just mentioned... OE? CC?
Aaaah, but of course...
