Whether you ride road, track days or both, this stainless and titanium assembly sharpens throttle response, frees up weight the chassis immediately notices, and delivers a soundtrack that matches the ZX-4RR's four-cylinder character without demanding a complete remap before you leave the paddock.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull system replaces headers and silencer: total weight drops from 9.4 kg to 4.7 kg — a 3.7 kg reduction that benefits handling as much as outright performance.\u003c\/li\u003e\n\u003cli\u003eStainless steel header construction for long-term corrosion resistance, daily commuting durability and consistent heat management.\u003c\/li\u003e\n\u003cli\u003eTitanium Force EVO slip-on silencer with carbon end cap — premium materials without the premium weight penalty.\u003c\/li\u003e\n\u003cli\u003eRemovable dB-killer lets you tailor the noise output: 105 dB at 7,500 rpm without it, or drop to 98 dB at 7,500 rpm using the specialist dB-killer set developed in collaboration with Kawasaki Deutschland.\u003c\/li\u003e\n\u003cli\u003eAll exhaust springs and a complete fitting kit are included so installation is straightforward from the first session.\u003c\/li\u003e\n\u003cli\u003eMade in Italy — hand-crafted in Spark's Italian facility for the quality tolerances that direct-fit performance parts demand.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality and Daily Usability\u003c\/h2\u003e\u003cp\u003eThe combination of a stainless steel header and titanium silencer is a considered choice rather than a cosmetic one. Stainless steel handles the sustained heat cycles and occasional moisture that road use brings, while titanium keeps the silencer mass low without sacrificing structural integrity. The carbon end cap is bonded cleanly to the titanium body, resisting the knocks of trackside paddock life as well as kerb-side urban parking.\u003c\/p\u003e\u003cp\u003eBecause the dB-killer is removable rather than permanent, you are not locked into one configuration. For road use or noise-restricted track day sessions, refit the killer and retain a 98 dB output using the specialist set. For open-pit-lane lapping, pull it and let the inline-four breathe fully at 105 dB. Both figures are measured at 7,500 rpm, so there is a genuine, quantified reference point rather than a vague claim.\u003c\/p\u003e\u003ch2\u003eTrack Development and Tuning\u003c\/h2\u003e\u003cp\u003eThis full system was developed in close collaboration with Kawasaki Deutschland, which means fitment geometry and back-pressure characteristics have been validated against the production ZX-4RR rather than extrapolated from a generic template. The improved throttle response is present from standard mapping, but Spark and Inter-Pace recommend a dedicated race map or a dyno session to realise the full potential of the freer-flowing system.
