M4 Dual Retro-Drag GP Slip-ons Exhaust System '12-'22 Kawasaki ZX-14R
M4's Retro-Drag slip-ons for the monstrous Kawasaki ZX14 are dual ceramic black slip-ons that give your ZX14 a new look and sound that will turn heads. This new product offers very noticeable horsepower increases that add to your already super-fast Kawasaki. The stock silencers have got to go since they are 20lbs. heavier than the M4 Retro-Drag slip-ons.
