Engineered and designed to let you feel every hi-rev note of the Ninja ZX-4R – RR, the CR-T slip-on muffler is the most iconic exhaust born for racing in MotoGP and Moto2 championships.

No other exhaust is like the original CR-T by SC-Project. It has a 100% racing DNA, with aggressive look and sound without compromise, especially in this racing version for the Kawasaki ZX-4R – RR.

For the Kawasaki ZX-4R – RR, the CR-T racing muffler allows an outstanding weight reduction of over -80% (-3.4 kg if compared to the OEM exhaust) and to get an incredible maximum gain of 6.0 hp at 13000 rpm and 3.5 Nm of torque at 13000 rpm, together with a stable improvement of power and torque delivery in the low and mid range.

The absolute top quality finish of the titanium outer sleeve, the TIG welding’s handcrafted in protected environment, the round and generous muffler output: all these elements are a pure joy for the look of the motorbike.

The silencers body is enriched by a precious aluminum riveted plate, the same used for MotoGP and Moto2 exhaust made by SC-Project Reparto Corse.

The installation is plug and play; ECU remapping is not necessary.
