    I looked at the resonator to plan a bypass pipe install, and found these rollers....wonder what the purpose is? That part will come off in the bypass pipe install.
    I have a 2014 Cali 30..

    Vibration dampers. They change the resonance frequency of the exhaust to aid in the reduction of vibration. You may or not notice the difference depending on the modifications you are doing to the exhaust.
