Description

SC Project Exhaust Kawasaki Z900 4-2-1 Stainless Steel Headers 2025+

Have your Kawasaki look and sound the way it should from the factory with these beautifully designed exhausts from SC Project.

The SC-Project header kit for the Kawasaki Z900 is the ultimate choice to maximise the performance of its four-cylinder engine. Developed by our R&D Department with a racing-focused approach, it is engineered to unleash the Sugomi Queen’s full potential.

This stainless-steel header system delivers a significant performance gain while noticeably improving agility. Thanks to a remarkable 50% weight reduction compared to the OEM exhaust system, the bike benefits from sharper handling and improved dynamics. Power increases by +8.8 hp at 10,200 rpm and torque by +7.1 Nm at 8,200 rpm. The system is designed to optimise exhaust gas flow, enhancing torque and power output, especially in the low- and mid-RPM range, where real-world performance truly matters.

It is built with top-level technical solutions such as TIG welding performed in a controlled environment and CNC-machined billet bushings, ensuring perfect fitment and making assembly extremely easy.

The removal of the original catalytic converter delivers a substantial drop in operating temperature and a true racing sound, with deep, loud notes. This kit is compatible with and optimised to work in combination with the SC-Project product range.

Please note: installation of this racing header kit does not comply with Euro 5+ homologation regulations. ECU remapping is recommended.

Together with this kit, the purchase of the SC-Project ECR+ (Electronic Catalytic Remover) is strongly recommended. After removal of the catalytic converter, the Kawasaki Z900 ECU may generate an error. This device has been developed by SC-Project to correctly manage the removal of the catalytic converter. Extremely easy to install, it simply connects to the OBD socket and will automatically manage the error, safely restoring the correct functionality of the on-board electronic system. It features an LED light that indicates the current operating status and an OBD cable splitter, allowing you to install it while keeping the OBD connection available for another device. You will find it in the related products section.

Technology and excellence, with no compromise, that is our philosophy
