Before and after - all SAE numbers. A 2009 Gen 2 . . . stock, it pulled 167.78 rwhp and 98.37 ft pounds torque. Add a Ti Force 4-2-1-2 titanium exhaust, some Ecu editor work, PCV powercommander, custom tuned: 193.53 rwhp at 116.47 ft pounds of torque. A gain of 25.75 rwhp and 18.1 ft. pounds. Peak torque hit at 7,100 rpm. Keep in mind these are SAE numbers . . . this bike should honk and this customer should feel a slight difference . . .
