Im new, to this site but, I have a question about my 02 yamaha r1 full akrapovic exhaust.... Basically I have full akra exhaust the muffler I have on it I would like to change only thing im see is the long cans, we when I bought the bike a cpl years ago it was obvious someone modified the muffler cut mad it shorter but, my thing is I qant to either turn my full exhaust into a shorty to clean the sid up if its possible and, also can I exchange my muffler with something more modern and, will it work?
