R9 (2025)

The new Yamaha YZF-R9 has quickly become the Yamaha R-series flagship, designed around lightness, performance and riding pleasure. Following the same philosophy, SC-Project developed a full exhaust system that pushes the R9’s dynamics to the next level. 

This product delivers a remarkable 65% weight reduction compared to the OEM exhaust, resulting in sharper handling and enhanced agility. Power and torque gains are outstanding with up to +7.0 hp and +5.5 Nm at 9500 rpm, along with a consistent enhancement in power delivery across the low and mid-range.

The headers are manufactured with high grade titanium, extremely light and featuring handcrafted TIG weldings. The CR-T  titanium muffler, it’s enriched by a distinctive honeycomb mesh on the outlet and by SC-Project’s logo, precisely etched with laser technology. To further refine the aesthetics of the R9, the kit includes a specific premium carbon fibre heat shield.

This complete exhaust system stands out as a benchmark in the segment, with a 100% racing-oriented design and the unmistakable acoustic signature that defines SC-Project. The sound of the three-cylinder engine is intensified by deep, aggressive tones, with 119 dB at 5000 rpm.

The installation of the kit is  100% plug and play and it’s completely reversible. ECU remapping is recommended to obtain the best performance.
