Measurements of the Akrapovic SLIP-ON EC Type approval system on the KAWASAKI ZX-6R (without muffler insert):
Power & Torque: the exhaust system modification with the SLIP-ON system results in a major boost in performance, delivering a massive 116.6 HP at 14100 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 4000 rpm up through entire rpm range. Max. increased power between the Akrapovic and the stock system is 2.9 HP at 14050 rpm. Besides this, the torque is substantially higher in a lower rpm area at 3000 rpm and from middle to high rpm area.
