SC-Project SC1-R Slip-On Silencer for Kawasaki ZX-10 R/RR (2016-2020) – Euro 4 Approved | K22A-T90

Developed in direct collaboration with the SC-Project racing division, the SC1-R slip-on silencer brings genuine circuit-derived technology to your Kawasaki ZX-10 R or ZX-10 RR — and crucially, it does so with full Euro 4 road-legal approval and EC type-approval included as standard. This is not a compromise between road compliance and race performance; it is both, without concession.

Key Features

• Euro 4 road-legal with EC type-approval — ride legally on public roads without compromise
• Hydroforming technology delivers aerodynamic efficiency and a purposeful, sculpted silhouette
• Asymmetric diamond-section carbon construction provides a racing aesthetic unique to the SC1-R line
• Hand-laid T.I.G. welds executed in a controlled environment for absolute structural integrity and longevity
• High-temperature acoustic damping material optimises both sound character and thermal performance
• Meaningful weight saving of 0.1 kg over the stock unit for a more agile feel through transitions
• Full-titanium connector fitting with T.I.G. technology for corrosion resistance and reduced overall mass

Road-Legal Racing Provenance

The SC1-R carries the Euro 4 homologation and EC type-approval that many rival aftermarket exhausts cannot offer. For ZX-10 R and ZX-10 RR owners who use their machine on the road as well as the track, this certification removes any ambiguity about legality. The approval is included in the package — there is no separate documentation to source or additional cost to absorb.

SC-Project's racing department shaped every dimension of the SC1-R around lessons learned in top-level competition. The hydroformed canister is not simply a visual exercise; it contributes to optimised exhaust gas flow that translates into a perceptible gain in mid-range response and a deeply characterful exhaust note — aggressive enough to announce your intent, controlled enough to pass noise checks.

Materials and Construction

Every component in the SC1-R reflects SC-Project's refusal to use anything other than competition-grade materials. The connecting pipe is machined from solid titanium, keeping thermal mass low and aiding weight reduction. The end cap — available in natural carbon or titanium finish — is heat-resistant and aerodynamically profiled to complete the visual package. Welds are performed in a shielded environment to prevent contamination, producing joints that are as strong as they are clean. The internal acoustic damping compound is selected specifically for high-temperature durability, ensuring the sound signature remains consistent across the life of the silencer.

Fitment and Compatibility

The SC1-R Slip-On in part number K22A-T90 is engineered as a direct-fit replacement for the following Kawasaki models:

• Kawasaki ZX-10 R — model years 2016, 2017, 2018, 2019, 2020
• Kawasaki ZX-10 RR — model years 2016, 2017, 2018, 2019, 2020

Installation requires no modification to the stock headers. The included full-titanium fitting, mounting springs, and hardware make this a genuine plug-and-play fitment. Part numbers by finish: Carbon — K22A-T90C; Titanium — K22A-T90T.
