Akrapovic Slip-On Line (Carbon) Ninja ZX-4R 23-

This beautifully designed exhaust has a more compact shape to fit with the bike’s naked and sporty appearance. It is constructed using hand-crafted carbon fibre parts and finished with a titanium end-cap in the same perfectly finished race-proven material. Power and torque increases throughout the range and a weight savings over the standard stock system all add to improved performance. It serves up an enriched tone for added aural enjoyment and is EC/ECE type approved. Easy-to-follow plug-and-play instructions with no remapping makes this a simple upgrade to improve the ZX-4R.
