Combining a stainless steel header with a titanium slip-on silencer and carbon end cap, this race-use-only system is engineered to liberate every horsepower the inline-four has to offer — from club days to full-on circuit assault.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRace-use only — designed from the ground up for maximum track performance on the ZX-4RR\u003c\/li\u003e\n\u003cli\u003eStainless steel header for superior heat resistance, corrosion resistance, and long-term durability under sustained high-revving use\u003c\/li\u003e\n\u003cli\u003eTitanium silencer body keeps unsprung weight to a minimum while withstanding extreme exhaust temperatures\u003c\/li\u003e\n\u003cli\u003eCarbon end cap adds a purposeful, competition-spec finish and further reduces overall weight\u003c\/li\u003e\n\u003cli\u003eStainless steel internal components within the slip-on for lasting durability in race conditions\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included — run it open on track or re-insert for noise-restricted sessions\u003c\/li\u003e\n\u003cli\u003eA custom ECU mapping tune is recommended to unlock the full performance benefit of this free-flowing system\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTrack-Focused Engineering\u003c\/h2\u003e\u003cp\u003eArrow's Competition range is developed with a single priority: outright performance on circuit. The 71233PTZ is not a road-legal exhaust — it is a pure race system, homologated for track use only. The combination of a mandrel-bent stainless steel header and a lightweight titanium can delivers optimised exhaust scavenging across the ZX-4RR's rev range, sharpening throttle response and improving top-end power delivery exactly where it matters on track.\u003c\/p\u003e\u003cp\u003eThe removable dB killer gives you flexibility at noise-restricted circuits without compromising the system's race-spec flow when run fully open. Arrow strongly recommends pairing this system with a dedicated ECU mapping session to ensure fuelling is optimised for the freer-flowing exhaust — a step that will make a measurable difference to both power and rideability on track.\u003c\/p\u003e\u003ch2\u003eBuild Quality\u003c\/h2\u003e\u003cp\u003eEvery material choice in the 71233PTZ has a clear purpose. Stainless steel on the header and internal components resists the thermal cycling and vibration that break lesser systems. Titanium on the silencer body saves meaningful weight high and to the rear — improving the ZX-4RR's mass centralisation. The carbon end cap is both a weight saving measure and a statement of race intent. This is an exhaust built to survive a full season of hard track use, not simply to look the part.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis Arrow Competition full exhaust system is designed specifically for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKawasaki ZX-4RR — model years 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThis is a direct-fit, race-use-only system.
