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 BMW S1000RR (without muffler insert):
Power & Torque: the exhaust system modification with the SLIP-ON OPEN system results in a major boost in performance, delivering a massive 188,10 HP at 13175 rpm on the back wheel. But the increased power isn't available just at the top of the range; the system shows its quality from 5500 rpm already up through the entire rpm range. Max. increased power between the Akrapovic and the stock system is 2,8 HP at 13160 rpm. Besides this, the torque is substantially higher in a lower rpm area and from middle to high rpm area.
