The muffler SC1-R is created and developed by the experience of the SC-Project racing department in the most important World Competitions. A look with taut and decided lines will enrich Your Yamaha YZF R1 making it unique and exclusive.

The exit pipe obtained by hydroforming and the carbon fiber end cap from the rhomboidal asymmetric shape make inimitable the silencer SC1-R. The lightweight outer body is available in both Titanium and Carbon version. The weldings with T.I.G., the sound-absorbing material resistant to very high temperatures and the insert bushings made in CNC machining embellish the SC1-R silencer. In the version with Titanium body the R&D department of SC-Project wanted to make the SC1-R more elegant by imprinting the Logo by laser, without distorting the look, while in the Carbon version, on the silencer is riveted an insert with the SC-Project logo as in the versions of our mufflers used in Competitions. In the kit are included the carbon heat protection and the Y 1-2 full titanium de-cat link pipe to guarantee the best performance.
