Spark Exhaust Grid-O Slip-On + CAT Replacement Pipe Kawasaki ZX-10 R/RR (2021-2026) GKA8843T

Dropping 1.7 kg from the Kawasaki ZX-10 R/RR exhaust system is one of the most cost-effective chassis upgrades you can make — and the Spark Grid-O 3/4 system (part GKA8843T) delivers exactly that, whether you're commuting hard or chasing lap times. A titanium mid-pipe replaces the OEM catalytic converter section, pairing with the Grid-O titanium slip-on silencer to bring total system weight down from 9.5 kg to just 7.8 kg, improving both throttle response and steering agility in the process.

Key Features

• Genuine weight saving of 1.7 kg over the stock exhaust — from 9.5 kg down to 7.8 kg — for sharper chassis feel and improved acceleration
• 3/4 system comprising a titanium CAT replacement pipe and the Spark Grid-O titanium slip-on silencer with carbon end-cap
• Removable dB killer gives you the flexibility to run full-open (approx. 110 dB at 5,500 rpm) on track or quieter on public roads
• Titanium construction throughout the header and canister for outstanding heat resistance and long-term durability
• Carbon end-cap adds a purposeful, race-derived finish while keeping weight to an absolute minimum
• Made in Italy — handcrafted to the exacting tolerances Spark Exhaust is known for across top-level road racing
• Complete mounting kit and exhaust springs included — no additional hardware required for installation

Everyday Usability Meets Track Performance

What makes the Grid-O 3/4 system a genuinely practical upgrade is the removable dB killer. Fit it for a quieter, road-legal character on your morning ride; pull it before a track day and the ZX-10 R/RR opens up to that hard-edged, aggressive note the system is tuned to produce. You're not compromising between one use or the other — the exhaust adapts around your riding schedule. The titanium mid-section also removes the restrictive OEM catalyst, freeing up exhaust flow and contributing meaningfully to the improvement in throttle response you'll feel from the first ride.

Build Quality and Materials

Spark Exhaust manufactures the Grid-O range entirely in Italy, using aerospace-grade titanium for both the replacement mid-pipe and the silencer body. Titanium offers an exceptional strength-to-weight ratio alongside natural resistance to the extreme temperatures generated under hard acceleration. The carbon fibre end-cap is a practical as well as aesthetic choice — resistant to heat, impervious to corrosion and noticeably lighter than an equivalent aluminium component. Every weld and joint reflects the craftsmanship that has made Spark a trusted name in club racing and professional paddocks alike.

Performance Notes

For the full performance benefit, particularly in tuned or race-specification ZX-10 R/RR builds, Spark Exhaust recommends using a dedicated race map or a custom dyno tune to optimise fuelling for the freer-flowing exhaust. On a standard or lightly modified machine, the improvement in throttle response and exhaust note will be immediately noticeable without any additional tuning.
