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

Enhance the performance and character of your Yamaha YZF-R9 with the SC Project 3:1 Full Exhaust System featuring the SC1-R Titanium Silencer. Designed with a strong racing focus, this system delivers impressive power gains, reduced weight and a refined, aggressive exhaust note.

Constructed using AISI 304 stainless steel headers and a lightweight titanium link pipe, this system ensures durability while significantly improving exhaust flow. The result is stronger throttle response and consistent performance gains across the rev range. The SC1-R titanium silencer features advanced manufacturing techniques including handcrafted TIG welds, a hydroformed asymmetrical outlet and a carbon fibre end cap, giving it a premium motorsport-inspired finish.

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