You will get the brand new set of OEM pipes that are pictured. These are no longer available from Norton, the reason is if you don't keep after the isolastics tunes up and keep them properly tight, then there is an interference with the pipes and the frame that can cause considerable damage. If you want to run these, you will have to keep after your isolastics, per the scheduled maintenance.
