Measurements of the Akrapovic SLIP-ON MEGAPHONE exhaust system on the SUZUKI GSX-R600 (without muffler insert):

Power & Torque: the exhaust system modification with the SLIP-ON system results in a major boost in performance, delivering a strong 114.4 HP at 13600 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 6000 rpm up through entire rpm range. Max. increased power between the Akrapovic and the stock system is 3.1 HP at 9280 rpm. Besides this, the torque is substantially higher in a lower rpm area at 3500 rpm and from middle to high rpm area.
