Spark Exhaust Full Titanium System Kawasaki ZX-10 R/RR (2021-2026) GKA8848T

Constructed entirely from aerospace-grade titanium — header, silencer body and end cap alike — the Spark Exhaust GKA8848T full system for the Kawasaki ZX-10 R/RR (2021–2026) is a masterclass in Italian fabrication. Every weld, every joint and every surface finish reflects a standard of craftsmanship that separates genuine race hardware from imitation performance parts.

Key Features

• Full titanium construction throughout: Titanium d.65 header, Grid-O silencer body and titanium end cap deliver exceptional strength, heat resistance and corrosion resistance in a single cohesive package.
• Dramatic weight saving of 4.6 kg — down from the stock system's 7.8 kg to just 3.2 kg — transforming chassis balance, turn-in response and overall agility.
• Removable dB killer included, allowing sound level adjustment to suit road, trackday or full race use; without the dB killer, measured output is approximately 105 dB at 5,500 rpm.
• Spark Grid-O slip-on silencer optimises exhaust flow for sharper throttle response and improved acceleration across the rev range.
• Compatible with original fairings and both stock and kit radiators, making installation straightforward without bodywork modification.
• Made in Italy — every unit is hand-finished in Spark's Italian workshop to exacting motorsport tolerances.

Build Quality and Materials

Titanium is the defining material choice here, and Spark uses it without compromise. The d.65 titanium header is drawn and shaped to optimise scavenging pulses on the ZX-10 R/RR's inline-four, while the wall thickness is kept to the minimum consistent with track durability — the result being a header that weighs a fraction of a steel equivalent yet handles sustained high-rpm heat without distortion or bluing that affects structural integrity.

The Grid-O silencer carries titanium from the inlet cone through to the end cap, maintaining thermal stability and resisting the surface discolouration and corrosion that afflict lower-grade alloys in wet or salty conditions. The Italian production process means tolerances are held tightly enough that the mounting bracket aligns perfectly with the original rear subframe — no drilling, no adaptation.

Performance and Sound

The combination of a free-flowing titanium header and the tuned internal geometry of the Grid-O silencer produces a measurable improvement in throttle response and mid-range pull, with peak power gains best realised through a dedicated race map or dyno session. With the dB killer removed, the system produces approximately 105 dB at 5,500 rpm — a deep, purposeful note that commands attention on the circuit without the artificial harshness of some aftermarket systems. With the dB killer fitted, the note is sufficiently subdued for open-road use in most jurisdictions.

Fitment and Compatibility

This full exhaust system is engineered specifically for the following models:

• Kawasaki ZX-10 R (2021–2026)
• Kawasaki ZX-10 RR (2021–2026)

The system is compatible with original OEM fairings and with both standard and aftermarket kit radiators. The complete mounting kit includes all exhaust springs and a dedicated bracket for attachment to the original rear subframe, ensuring a clean, rattle-free installation.

For maximum performance gain, Spark and Inter-Pace both recommend pairing this system with a purpose-built race map or a professional dyno tune to fully unlock the potential of the freer-flowing exhaust.
