Graves Motorsports say the performance gains for their FZ07 Exhaust System are significant with a strong increase in torque and power from 2,500 rpm to peak rpm, featuring a full 5-6 Horsepower gain on top end. Graves also claim that when compared to the stock street system, the full Graves Ti Performance System offers a weight savings of 10.8 lbs. The Graves Diamond Shaped Carbon Silencer included with the Ti System is similar to the ones used on their factory Superbikes and enhances the look of the Yamaha FZ07, and mounts directly to the motorcycle by using a stealth carbon fiber strap, saving weight and streamlining looks. The Silencer comes standard with a GMS exhaust insert to quiet the sound, which is removable. This System is design for closed course off-highway racing use only, and will perform best with the optional Graves FTECU Flash mapping upgrade available from Graves.
