i agree, i love my stock gear indicator but i wouldn't buy one if it wasn't on there... i hear the aftermarket ones are a pain to install, and figure out your gear by an equation on road speed and engine speed so theres a delay from the time you shift to the time it shows up

exhaust, like he said again, you can't go wrong putting graves on an r1, haven't seen or heard yosh on one, but i've heard graves, sick, heard arata, sick... akrapovic is always going to be top quality but they generally seem to be a bit quieter than most
