Have you tried Tec Bike Parts, they may do one?

 

I wonder why Motone have stopped producing their X-pipe. A shame. I've got one on my bike and it's a very well made bit of kit, better than TEC.
If you haven't already tried I would phone Motone and ask if they have any stock left. I've spoken to Dan at Motone on several occasions over the years and always found him to be very resourceful.
