Description
xEngineered and designed to let you feel every hi-rev note of the Ninja ZX-4R - RR, the S1 racing muffler is the perfect combination of lightness, design and SC-Project signature sound.
The conical body shape enriched by SC-Project lasered logo and the elegant carbon fibre end cap, make the S1 silencer a benchmark in terms of aesthetic and sound emotion. The absolute top quality finish of the outer sleeve in ultra-light titanium, the TIG weldings handcrafted in protected environment, the accuracy of the carbon fibre end cap shape, are a pure joy for the look of the little Ninja.
For the Kawasaki ZX-4R - RR, the S1 racing muffler allows an outstanding weight reduction of over -65% (-2.9 kg if compared to the OEM exhaust) and to get an incredible maximum gain of 5.0 hp at 13000 rpm and 3.0 Nm of torque at 13000 rpm, together with a stable improvement of power and torque delivery in the low and mid range.
Everything has been developed to offer a superbe sound experience and for this racing application the muffler comes with a removable dB-killer: the strong and deep sound of the S1 exhaust will be totally unforgettable.
The installation is completely plug and play; ECU remapping is not necessary.
