4-2-1 Header Configuration

The system uses a 4-2-1 header configuration. This layout replaces the original header section and forms the foundation of a complete SC-Project exhaust system.

Furthermore, SC-Project designed these headers specifically for the Kawasaki Z900. The system also works with compatible SC-Project Slip-On mufflers made for this motorcycle.

Stainless Steel Construction

The headers use SAE 304 stainless steel. This material provides a strong and durable foundation for the complete exhaust setup.

In addition, SC-Project offers its complete systems in AISI 304 stainless steel or full titanium versions. This particular configuration uses stainless steel headers. Therefore, it combines robust construction with a performance-focused design.

Power and Torque Gains

The SC Project 4-2-1 Stainless steel headers, compatible with specific SC-Project range- Kawasaki Z900 (2020) deliver measurable performance gains.

The system provides up to +8.8 hp at 10200 rpm. It also delivers +7.1 Nm of torque at 8200 rpm.

As a result, the headers can significantly enhance the performance potential of the Kawasaki Z900 when used with the compatible SC-Project exhaust configuration.

Significant Weight Reduction

The SC-Project headers weigh 4 kg. The OEM exhaust system weighs 8.3 kg.

Therefore, the system reduces weight by 4.3 kg compared with the original setup. This substantial reduction can contribute to a lighter overall exhaust configuration.

Moreover, the lower exhaust weight supports the performance-focused character of the complete SC-Project system.

Original Lambda Probe Compatibility

The headers support the original lambda probe. This allows the system to retain the motorcycle’s existing lambda sensor.

SC-Project specifically designed the full system to house the original lambda sensor. Therefore, the supplied header configuration maintains this important sensor integration.

Catalytic Converter Removal

The complete SC-Project system removes the original catalytic converter. According to the supplied product information, this change allows a significant reduction in operating temperature.

Furthermore, removing the original catalyst contributes to the deeper and darker exhaust sound associated with SC-Project systems.

Deep and Dark Exhaust Sound

The complete configuration gives the Kawasaki Z900 a deep and dark exhaust sound. This acoustic character forms part of the distinctive SC-Project exhaust identity.

Moreover, the combination of the 4-2-1 headers and compatible SC-Project muffler creates a complete performance-oriented exhaust setup.

Compatible SC-Project Slip-On Range

These headers are designed to work with the compatible SC-Project Slip-On muffler range for the Kawasaki Z900.

Therefore, riders can pair the headers with a suitable SC-Project muffler designed for this motorcycle. Always confirm the specific muffler compatibility before purchasing or installing the system.

ECU Tuning Recommendation

For better performance, SC-Project recommends installing an additional control unit or remapping the standard ECU.

This tuning step can help match the motorcycle’s engine management to the modified exhaust configuration. Therefore, ECU tuning should form part of the installation plan when seeking the stated performance potential.

Racing Development

SC-Project developed the complete system through its in-house R&D department. The development also draws from technical work with major MotoGP and SBK championship teams.

As a result, the headers reflect a racing-focused engineering approach. They bring this development experience to the Kawasaki Z900 through a dedicated 4-2-1 configuration.

FOR RACING USE ONLY

The SC Project 4-2-1 Stainless steel headers, compatible with specific SC-Project range- Kawasaki Z900 (2020) are marked FOR RACING USE ONLY.

Therefore, this header system is intended for racing or closed-course applications. It should not be treated as a road-legal exhaust component unless the applicable approval for the exact configuration confirms otherwise.

Final Overview

The SC Project 4-2-1 Stainless steel headers, compatible with specific SC-Project range- Kawasaki Z900 (2020) provide a complete foundation for a high-performance SC-Project exhaust setup.

They deliver +8.8 hp and +7.1 Nm, while reducing exhaust weight by 4.3 kg compared with the OEM system. In addition, the SAE 304 stainless steel construction supports the system’s durable performance-focused design.

The headers accommodate the original lambda probe and work with compatible SC-Project Slip-On mufflers. For better performance, SC-Project recommends an additional control unit or standard ECU remapping. FOR RACING USE ONLY.
