News A breath of fresh air for the Yamaha R9 with SC-Project

Italian exhaust specialist SC-Project unveils its lineup for the already famous Yamaha R9. On the menu: two lines (with titanium or carbon fiber mufflers) combining cutting-edge technology and performance, featuring Euro 5+ certification and a radical track-only version.

The demand for controlled performance (Euro 5+)

As environmental standards tighten, SC-Project proves that legality and riding pleasure can go hand in hand. The Italian manufacturer has developed a high-performance stainless steel catalytic converter that strictly complies with the Euro 5+ standard.

In terms of manufacturing, the equipment manufacturer makes no compromises. The design incorporates solutions directly derived from racing:

• Laser cutting and TIG welding;
• CNC-machined titanium clamps;
• High-precision assemblies guaranteed to fit without modification to the original vehicle.

Two mufflers, two philosophies

To complete this homologated line, riders can choose between two of the brand’s flagship models:

• The iconic CR-T: The minimalist choice. With its GP prototype look and honeycomb grille, this silencer (titanium or carbon) prioritizes compactness. It delivers a 1.1 hp gain while producing a deeper sound.
• The versatile SC1-R: A "best-seller" with a more generous volume and an asymmetrical hydroformed tip. Derived from the Superbike, it proves more effective on the dyno with a 3 hp gain and a torque increase of 2.5 Nm at 9,500 rpm.

The Racing Line: The CP3’s fury on the track

For those who trade the road for the stopwatch, SC-Project offers an unhomologated variant. This complete line ditches the catalytic converter in favor of a titanium 3-into-1 manifold.

The numbers speak for themselves:

• Power gain: Up to +7 hp (with CR-T muffler);
• Torque: An increase of 5 Nm at 9,500 rpm;
• Weight: A drastic weight reduction of 4.8 kg compared to the stock part.

Note: While the SC1-R remains reasonable at 101 dB (with a silencer), the CR-T embraces its racing DNA with a sound level of 119 dB, enough to let the Japanese three-cylinder engine sing in all its glory.
