Unlock the True Potential of Your Ninja 1000 SX

Transform the performance profile of your Kawasaki with the Arrow Racing Collectors (Part #71728MI). Designed to replace the restrictive stock headers and catalytic converter, this full stainless steel header system drastically improves exhaust gas flow, reduces weight, and unleashes the raw sound of your inline-four engine.
