Pure power is not the only thing to consider when it comes to performance upgrades. For those riders carving up the mountains, or still wishing to take a corner with speed, you need corner clearance as well and the Vance & Hines Up Sweep 2-Into-1 Exhaust has plenty of it. Oh, did we mention this also gives pure power? The finely engineered 2-into-1 design will increase your bike's power output, while providing a nice bark to the exhaust note.
