Ok first you have a Roadster so none of the OEM exhaust from older non Roadster Rockets will work do to your ABS system. Also the Touring pipes hang from the hard bag frame mounts which you do not have so without modification no touring pipes will fit. Except for the lousy power robbing tractor header. You will be lucky to purchase a Jardine system for the Roadster and if so it will be used. The older Jardine pipes will not work because of the ABS box behind the engine on the right.
You already know the after market headers and systems are pricey. Probably not what you want to hear. If you look around you will see a few cans that were adapted to the header but not much.
If your not wanting to spend a lot look around for a set of used TORS.
