if you are just talking cans and not full system then the difference would be very minor, as Pete has said any change to the exhaust really needs to be flashed to get the bike running properly and smoothly. On my last gen 2 I had the R77 carbon yoshi cans and then got Pete to flash it, and it had 181 rwhp, plus it ran much smoother.
