Developed and designed by our R&D department, this street-legal full exhaust system for the Yamaha R9 represents the perfect fusion of performance, craftsmanship, and innovation. Fully compliant with Euro5+ regulations, it delivers a significant increase in power. 100% Made in Italy with premium materials, it features SC-Project’s unmistakable sound, making it the best choice for riders seeking real racing technology on the road.

Manufactured of extremely resistant AISI 304 Stainless Steel, this full system offers a great improvement of the performance of the japanese supersport, thanks to an astonishing gain of 3,0 hp and 2,5 Nm at 9500 rpm together with a consistent enhancement in power and torque delivery across the low and mid-range.

This full system is completed by SC-Project top-of-the-line muffler: the SC1-R. It showcases our most advanced production processes like handcrafted TIG weldings performed in a controlled environment, an asymmetrical outlet obtained with hydroforming technology and finally a unique and sporty carbon fibre end cap.

The kit also includes two high quality carbon fibre protections:
one heel guard specifically designed to protect the link pipe, and one specific heat shield.

To further refine the look of the bike, the carbon fibre muffler’s body is completed by an exclusive aluminium riveted plate with 3D-embossed SC-Project logo, identical to those used by our Racing Department.
