It's not just about peak power--Akrapovic exhaust systems deliver increased performance throughout the entire rpm range. Increased power and torque result in a much smoother ride. All Akrapovic exhaust system measurements are made on our computer-controlled chassis dynamometers.
Measurements of the Akrapovic SLIP-ON system on the APRILIA DORSODURO 750 (without muffler insert):
Power & Torque: the exhaust system modification results in a major boost in performance, delivering a solid 84.8 HP at 9540 rpm on back wheel. But the increased power isn't available just at the top of the range; the system shows its quality already from 3500 rpm up through entire rpm range. Max. increased power between the Akrapovic and the stock system is 1.8 HP at 9300 rpm. Besides this, the torque is substantially higher in a lower rpm area from 2500 rpm to 6500, and also in middle and high rpm area.
