Hey guys, bought an R1 a few weeks ago, was just wondering if anyone here had unrestricted their and if made a noticable different. Also this bike is bone stock so was looking at a Yoshi RS-3 slip for is. I was at Bikebiz today buying some new fairing screws and over-heard one of the guys working there telling a customer that carbon fiber exhausts sound a little deeper than others because that are a natural material, now I though the baffle determined all that lol, I'm no exhaust expert but a 2nd opionon would be handy. Are there any places anyone would recommend to tune the bike after its been fitter with a Yoshi RS-3 and K 'n' N high performance air filter??
