All the info is in the above link. Bear in mind you can't just fit an end can. The 650 takes a 3/4 system which makes them fiddly to fit on the rear cylinder and a bit more expensive than a simple end can. However, it's well worth it to hear the gorgeous v-twin growl normally stifled by a stock exhaust. My money's on the Fuel but there are many alternatives out there. Go for it!
