Hmmmm....
They're only standard pipes, but if/when you sell the bike did come with them, and the race pipes, stand, cover and plaque, to me it's a complete package.... otherwise it's going to be sold at a lower price as and when you sell, probably less than what you might get for the standard pipes...
Plus I guess it depends on who you sell it too...
I've got a house full of spare kit that came with the bike, and the Bostrom which when they go I'll bundle with them to hopefully aid selling...
