Exhaust value?
 

Hi guys,

I got these two carbon exhausts with my bike.

Apparently the bike used to have duel under-seat exhausts.
They look in pretty good condition, have no baffles or e markings. They do have Yoshimura stickers on them, but one in particular is fading so probably are not genuine.
No brackets or link pipes.

I'm not going to use them, may as well sell, but have no idea of their worth.

Any ideas?

Mods - sorry if this is in the wrong section; I didn't think it could go in the 'for sale' section as I have no price! Please move though if it is wrong ;)

I'd guess maybe £100 to £150 for both?
