Here is the exhaust extension that I have. I also have the bracket, rear fender and rear fender support. Since it all bolts together, it would be convenient to get it all at the same time. I would be willing to ship everything together for $80.

If yours uses the butterfly kickstand, I have it as well -- $20 shipped:
The only other thing I have left is the front forks and front wheel. I have no idea what to ask for the forks, but I have $30 shipped on the wheel.
