Yamaha YFZ450R -  Rossier exhaust wakes up the fuel injected YFZ by increasing the peak power from 38 to 47 HP at the rear wheels. The RE also completely eliminates the stock sag at 3800 RPM that is present with the stock pipe.

Yamaha YFZ450 - Rossier Exhaust will earn you 8.4+ peak HP, and 10.5 HP at 10,000 RPM over the stock exhaust!  You'll also gain an additonal 1.5 hp at peak and a extra 3.5HP by rotating the exhaust cam 1 tooth.
