Graves LINK Stainless Header Upgrade Kawasaki Ninja 400 / Ninja 500 / Z400 / Z500

If you are already running a Graves slip-on and looking to wring every last bit of power out of your twin-cylinder lightweight, the Graves LINK Stainless Header Upgrade is your ticket to a true full-system setup. This header replaces your restrictive stock front section, unlocking optimal exhaust flow, reducing weight, and sharpening throttle response across the rev range.

Crafted with the same Championship-winning engineering that Graves brings to AMA Superbike, this header utilizes premium-grade stainless steel tubing with tapered downpipes tailored specifically to the engine's power delivery. Precision laser welding ensures immaculate seams and long-term durability under harsh track conditions. The billet 7075-T651 aluminum flanges are hard-anodized for supreme strength, and spring-assisted mounts make installation and maintenance straightforward for track day prep.
