Come on now lets be serious. Of course it needs a new link pipe to fit correctly... If it stays which will not.
I just wanted to hear the difference between the little aftermarket slip-on and the stock one. It actually surprised me how much quieter it is especially at low RPMS. Also I thought the bike runs smoother in the very low RPMS. Is that possible or is it just perception like when you turn the radio volume down when looking for a parking spot?
