Inspired by the Vance & Hines Race Team competing in the King of the Baggers class of the MotoAmerica Road Racing Championships, the Hi-Output RR captures every pulse-quickening element of our racing exhaust system into one you can put on your Milwaukee-Eight Road Glide or other Touring model as part of your own performance bagger build. Features innovative PCX (Power Chamber Exhaust) technology, which integrates a chambered high-flow catalyst for a bigger boost in torque off the line and roaring out of the corners.
