It's too bad that the FMF q4 for this bike is so loud (sounds like at the 96db limit they advertise) I have had Q2/4 slip ons in the past and they were significantly quieter than this seems to be. I applaud FMF for getting it to market and all their efforts at sound reduction, yet this is disappointing.
