Description
SC Project Exhaust Yamaha YZF-R9 3-1 Stainless Steel Full System + SC1-R Silencer 2025+
Have your Yamaha look and sound as it should, straight from the factory, with this beautifully designed SC Project exhaust.
Developed by our R&D department, this street-legal full exhaust system for the Yamaha R9 blends high performance, craftsmanship, and innovation. Fully Euro 5+ compliant, it delivers a clear power increase and SC-Project’s unmistakable sound, bringing real racing technology to the road.
Made from high-strength AISI 304 stainless steel, it boosts the R9’s performance with gains of 3.0 hp and 2.5 Nm at 9,500 rpm, and improves power and torque across the low and mid-range.
The system is completed by our flagship SC1-R muffler, featuring handcrafted TIG welds, a hydro-formed asymmetrical outlet, and a sporty carbon-fibre end cap. The carbon-fibre body is finished with an aluminium riveted plate with 3D-embossed SC-Project logo, identical to those used by our Racing Department.
The kit includes a dedicated premium carbon-fibre heat shield to enhance the R9’s aggressive look. Installation is plug-and-play, fully reversible, and requires no ECU remapping.
