Hi, The Yoshimura rs5 on my 2004 cbr is loud, too loud for my ageing ears. So I’d like to fit a lower volume insert or decibel killer to quieten it down a bit. Yoshimura don’t make them any more but I thought that someone might have an unused, unwanted and unloved one that they are willing to sell to me. I’ve attached photos of the desired item and the exhaust into which it has to fit. Thanks, Phil
