The ZX 6-R, Kawasaki?s speedster in the 600 class, is definitely a head-turner. To improve its sleek looks even further we have developed an Akrapovic SLIP-ON system which fits smoothly into the lines of the Kawasaki. The Akrapovic SLIP-ON exhaust system is designed for riders who are looking for an excellent combination of aesthetics, quality and price. System is available in street legal and sportier open version.      Performance  Measurements of the Akrapovic SLIP-ON system on the KAWASAKI ZX 6-R (without noise damper):  Power & Torque: Akrapovic power curve follows the stock curve up to 6000 rpm, and then shows an noticeable increase which extends right into the overrev range. The ZX 6-R receives 117,8 HP at 14325 rpm, which is 3 HP more than with stock exhaust system.
