Yamaha R9 (2025-2026) 3-1 Titanium full exhaust system, with CR-T titanium exhaust, with stoneguard grid

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.

Together with this kit, the purchase of SC-Project ECR (Electronic Catalytic Remover) is strongly recommended. With the removal of the catalytic converter, the motorcycle’s ECU could 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 needs to be connected to the OBD socket and it will automatically manage the error, safely restoring the correct functionality of the on-board electronic system.
