I just got my R1 and it is pretty much stock, except for a few cosmetic parts. Right now my funds allow me to purchase either a full system exhaust with PC, or a track suit...What do you guys think? Track riding, or piping upgrade? Also for those who have a full system with remap (seems like most do on this forum hehe), how much of a difference did you feel? Is it significantly noticable? Thanx in advance.
