Hi Shrek,
I have a Standard Yamaha FZS 600 2002 Silencer that you are more than welcome to as a gift.
The condition is very good I will take some pics, it has a small scratch on the end (Not a dent) where I dragged it on the corner of my house wall while pushing the bike.
with a bit of patience and some very fine wet-n-dry and soapy water you may very well be able to get rid of the mark.
Where about's are you, cos its heavy and would cost a fair amount to post.
I am in Hampshire about 20 miles North of Portsmouth, but I am driving to Cambridge tomorrow if that is any help direction wise.
The silencer has all the fittings and anchor/mounting bolts.
