But the increased power isn’t available just at the top of the range; the system shows its quality already from 5500 rpm up through entire rpm range. Max. increased power between the Akrapovic and the stock system is 7.8 HP at 14500 rpm. Besides this, the torque is substantially higher in a lower rpm area at 5000 rpm and from middle to high rpm area.
