Spark Exhaust Force EVO Slip-On + Cat Replacement Pipe Kawasaki ZX-10 R/RR (2021-2026) GKA8844T

Spark Exhaust has built its reputation on Italian craftsmanship and uncompromising engineering — and the Force EVO 3/4 system for the Kawasaki ZX-10 R/RR distils that heritage into one of the most visually striking and technically accomplished exhausts available for the 2021-2026 generation. Full titanium construction, a carbon end cap and the unmistakable Force EVO silhouette make this system as much a design statement as it is a performance upgrade.

Key Features

• 3/4 system pairing the Force EVO slip-on silencer with a cat replacement pipe, delivering a measurable 2.5 kg weight reduction (from 9.5 kg down to 7.0 kg).
• Full titanium pipe and silencer construction for outstanding heat resistance, corrosion resistance and lasting durability.
• Carbon end cap adds a race-bred aesthetic and complements the natural titanium finish of the collector pipe.
• Removable DB-killer allows sound level adjustment — run it closed on the road or pull it out for track use; measured output is 110 dB at 5,500 rpm without the DB-killer fitted.
• Optimised throttle response and improved performance across the rev range, with the cat replacement pipe freeing the exhaust flow for maximum effect.
• Retains compatibility with OEM fairings, radiators and rearsets — a straightforward bolt-on fitment with no ancillary modifications required.
• Made in Italy: every weld and finish reflects Spark Exhaust's artisan production standards.

Design, Finish and Heritage

The Force EVO line is where Spark Exhaust's Italian design philosophy is most visible. The silencer's sculpted titanium canister develops a characteristic heat-blued patina over time, giving each unit a finish that is genuinely unique to the way you ride. The carbon fibre end cap provides a deliberate visual counterpoint — deep black weave against the warm metallic tones of the titanium body — a combination that has become a signature of Spark Exhaust's premium tier.

Spark was founded on the premise that an exhaust should look as purposeful as it performs. The Force EVO embodies that philosophy: clean Italian lines, a slim profile that sits tight to the tail unit, and a level of material quality that ages with character rather than showing wear. Compared with the standard Kawasaki exhaust, the reduction in unsprung and rotating mass is immediately perceptible, sharpening turn-in response and reducing the inertia the chassis has to manage under hard acceleration.

Performance and Track Use

Replacing the OEM catalytic converter section with the dedicated Spark cat replacement pipe is central to unlocking the system's potential. Removing the restriction of the cat allows exhaust gases to evacuate more freely, improving mid-range torque delivery and top-end power on the ZX-10 R/RR's inline-four. The Force EVO silencer is engineered to complement this flow, with internal baffling geometry tuned alongside the pipe to produce a broad, aggressive sound character that rewards hard riding without the flat, artificial note of a poorly matched aftermarket can.

For track use, Spark recommends fitting a purpose-built race map or carrying out a full dyno session to extract the maximum performance gain the system is capable of delivering. Running the cat replacement pipe on public roads may not be permitted in all jurisdictions — please check local regulations before use.
