Measurements of the Akrapovic SLIP–ON open system on the DUCATI Streetfighter without muffler insert:
Power & Torque: The Akrapovic SLIP-ON open system greatly increases the potential of the big twin cylinder engine. Both power and torque are increased over the entire rpm range, with the greatest increase shown in the middle and top of the range. We measured 147.79 HP at 9929 rpm, while the max. increased power of 4.95 HP was measured at 9850 rpm. That results in a much smoother ride as the biggest gain of power starts from 4500 rpm.
