Yasuni high pipe for the Derbi FD and FDS enduro series.
Large chamber exhaust. Probably best for kitted bikes or ported stock cylinder with a larger carburetor. Very nice looking baffle that comes apart for rebuilding.
Comes with everything pictured. Looks like you might have to source a metric bolt for the rear hanger. Nothing special there though.
These are new old stock exhausts. They are in great shape but still quite old so expect very minor blemishes from storage.
