SC Project 3:1 Stainless Steel System SC1-R Carbon Fibre Silencer Yamaha YZF-R9 2025-26

SC Project 3:1 Full System with SC1-R Carbon Fibre Silencer for Yamaha YZF-R9 

Take your Yamaha YZF-R9 to a new level with the SC Project 3:1 Full Exhaust System featuring the SC1-R Carbon Fibre Silencer. Designed with a strong focus on performance and racing DNA, this system delivers substantial power gains, reduced weight and a distinctive motorsport-inspired sound.

Built using AISI 304 stainless steel headers and a lightweight titanium link pipe, this system offers excellent durability while significantly improving exhaust flow. The result is enhanced throttle response and a noticeable boost in power and torque across the rev range. The SC1-R carbon fibre silencer features advanced construction techniques including TIG welds, a hydroformed asymmetrical outlet and a carbon fibre end cap, creating a premium finish that complements the aggressive styling of the R9.

This is a plug-and-play solution with fully reversible installation. ECU remapping is recommended for optimal performance due to the decat configuration.
