Hi all, I am wanting to get an aftermarket can for my 2007 R1. I have been thinking about getting an akropovic, yoshimura or leo vince. Does anyone have any advice on which is the best for the R1? I also wanted to know if it is essential to get the bike remapped if I bought one, if so, what I would need to purchase e.t.c? Thanks for you help.
