DescriptionThe whole story▼

Built for riders who demand race-grade performance from every session, the Spark Exhaust GKA8803T full system transforms the Kawasaki ZX-10 R and ZX-10 RR into a sharper, freer-breathing machine. A 304 stainless steel header feeds a titanium Spark Force slip-on silencer measuring 350 mm, delivering optimised throttle response and measurably improved output across the rev range.

Key Features

  • Full system design maximises scavenging efficiency and throttle response — not just a slip-on upgrade.
  • 304 stainless steel header: corrosion-resistant, built to withstand sustained high-temperature track use without distortion.
  • Titanium 350 mm Spark Force silencer cuts unsprung and overall weight significantly compared to the stock unit, sharpening chassis dynamics.
  • Titanium end cap completes the race aesthetic while adding further resistance to heat discolouration.
  • Removable dB killer included — fit it for a quieter setting or pull it out entirely for the circuit.
  • Handcrafted in Italy: precision TIG-welded construction and quality control to exacting race-team standards.
  • Complete fitment kit included — all exhaust springs and mounting hardware supplied for a straightforward installation.

Performance & Construction

The choice of 304 stainless steel for the header is deliberate: it offers the wall thickness and rigidity needed to handle the ZX-10 R's aggressive power delivery while resisting the thermal cycling that cracks lesser systems. The step up to a titanium canister is where the GKA8803T really separates itself from budget alternatives — the weight saving translates directly into a more responsive front end and faster direction changes, both of which matter acutely on a circuit where every tenth counts.

The Spark Force silencer is tuned to deliver a deep, purposeful exhaust note that signals intent without sacrificing the mid-range torque the ZX-10 R is known for. With the dB killer removed, the system opens up fully, rewarding precise throttle inputs with an immediate and linear response that makes corner exits significantly more satisfying.

Road to Race Flexibility

The removable dB killer means this system works equally well as a weekend road upgrade and a dedicated track weapon. For closed-circuit use, Spark Exhaust and Inter-Pace both strongly recommend a race map or dyno tune to extract the full performance potential of the open exhaust flow — running a stock ECU map with a full system leaves power on the table and can lean out fuelling under hard acceleration.

Fitment & Compatibility

This full exhaust system is designed and manufactured specifically for the following motorcycles:

  • Kawasaki ZX-10 R (2016-2026)
  • Kawasaki ZX-10 RR (2016-2026)

No cutting, drilling or frame modification required. All mounting points align with the factory positions using the supplied hardware.

Road Approval

None. Spark lists this part as racing: it carries no EC homologation certificate. It must not be fitted to a motorcycle ridden on public roads, and a fitted dB killer does not change that.
