1st Ducati.......Love it

Hi
Had a 2007 s2r 800 for a few months now and need some recognised end cans, or full exhaust set up. I feel naked without!! I have had a look on the web and it seems that Termi are the ultimate, but sadly out of the question due to cost.

Are there any althernative?
Does anyone have a used set for sale?
Can I mount a set of exhausts on either side of my model -they are currently shotgun style.

Any advice greatly appreciated.......
