SC Project SC-RR Carbon Fibre Underseat Silencer Honda CBR600RR 2024-26

The new Honda CBR600RR revives one of the most iconic supersport styling cues of all time — the undertail exhaust.

To celebrate this return, SC-Project has developed the SC-RR Carbon Fibre Silencer, a lightweight, high-performance, and race-inspired exhaust designed specifically for the CBR600RR.

Manufactured from premium carbon fibre, the SC-RR delivers a significant weight saving of over 25% (-1.1 kg compared to OEM) while boosting engine performance by up to +1.5 hp and +1.7 Nm at 7500 rpm. Alongside the measurable gains, it ensures a smooth power delivery across the low and mid-range, giving riders both agility and performance.

The SC-RR also provides an enhanced sound experience. The 600 cc four-cylinder engine gains a deeper, more aggressive tone, while remaining fully compliant with Euro 5+ regulations. Finished with handcrafted TIG welds, a newly designed carbon fibre end cap, and a sharp-edged debossed SC-Project logo, this silencer combines performance with premium styling.

For further refinement, the kit includes a pair of carbon fibre covers that completely replace the OEM units, complementing the underseat exhaust design and improving the overall appearance of the CBR600RR with the stock license plate holder. Installation is 100% plug-and-play with no ECU remapping required.

SC-Project is proud to be the official and exclusive exhaust supplier for the Italian “Pro Honda CBR600RR Cup,” developed in collaboration with Honda Italy.
