Spark Exhaust WSBK Replica Full Exhaust System Kawasaki ZX-10 R/RR (2016-2020) GKA8815T

Conceived alongside the WSBK Go Eleven and Orelac racing teams, the Spark Exhaust WSBK Replica full exhaust system for the Kawasaki ZX-10 R/RR (2016-2020) is constructed entirely from aerospace-grade titanium — headers, silencer body and end cap — delivering the kind of weight reduction and thermal resilience that defines genuine superbike engineering. Part number GKA8815T, made in Italy.

Key Features

• Full titanium construction throughout: headers, slip-on silencer body and end cap for maximum weight saving and long-term durability
• Developed in direct collaboration with WSBK factory-supported teams Go Eleven and Orelac — race-proven geometry and flow characteristics
• 107 dB measured output at 5,500 rpm delivers an aggressive, authentic superbike soundtrack on track
• Removable db-killer allows the sound level to be adjusted between road use and unrestricted track sessions
• Full titanium headers improve throttle response and optimise gas flow from the cylinder head back, sharpening mid-range and top-end delivery
• Complete installation kit — all exhaust springs and mounting hardware included, no additional parts required
• Italian craftsmanship: hand-finished in Italy to the exacting tolerances expected at World Superbike level

Build Quality and Materials

Where most aftermarket systems compromise with stainless steel headers capped by a titanium can, the GKA8815T takes a different approach: every component in the exhaust path — from the primary header pipes through to the silencer end cap — is fabricated in titanium. The material's exceptional strength-to-weight ratio strips significant mass from the front of the bike, lowering rotational inertia and improving the ZX-10 R's inherent agility. High heat tolerance prevents discolouration and fatigue at the extreme exhaust gas temperatures generated by Kawasaki's inline-four, meaning the system stays structurally sound race after race.

The Spark SBK Replica silencer replicates the unit run by Go Eleven and Orelac in the World Superbike Championship, so the visual connection to the World Superbike paddock is genuine rather than cosmetic. Italian manufacturing standards ensure precise fitment without modification to the stock mounting points.

Performance and Sound

At 107 dB (measured at 5,500 rpm) this system is unambiguous about its intentions. On track, with the db-killer removed, the ZX-10 R delivers an unrestricted race note that matches the visual drama of the titanium finish. For road riding or noise-restricted circuits, the included db-killer inserts quickly to bring the output to a more manageable level without tools.

To extract the full performance benefit of the freer-flowing exhaust path, a dedicated race map or a custom dyno tune is strongly recommended. Optimised fuelling unlocks the improvements in throttle response and top-end power that the titanium headers and enlarged gas flow path make possible.

Fitment and Compatibility

This full exhaust system is a direct-fit replacement for all Kawasaki ZX-10 R and ZX-10 RR models from 2016 to 2020. All exhaust springs and mounting hardware are supplied in the box; no proprietary brackets or additional adapters are needed for a clean installation.
