The Spark Exhaust Stainless Steel Grid-O Complete System for the Kawasaki ZX-4RR (2023-2026) has been specifically designed for racetracks and championships without decibel restrictions, providing outstanding performance enhancement and a massive weight reduction of 3.6 kg (from 9.4 kg to 5.8 kg). The Grid-O end silencer is already used on Moto2 and Superbike World Championship racetracks, highlighting its excellent performance and aggressive sound.
With a combination of titanium for the end silencer and stainless steel for the header, this complete system not only improves chassis dynamics but also offers exceptional temperature resistance and durability. The dB killer (G9980) is included in the kit and can be installed as needed to regulate the noise level.
The complete system is compatible with the original passenger footpeg and comes with a special bracket for mounting the silencer on Chassis. An additional bracket for the Chassis is optional to further customize the exhaust system to the rider's individual needs.
