Stainless steel headers, a titanium slip-on silencer and a carbon end cap combine race-derived materials with genuine road legality, giving every YZF-R7 rider a complete, bolt-on upgrade that looks as purposeful as it performs.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRoad-legal full system with E-approval number for unrestricted use on public roads\u003c\/li\u003e\n\u003cli\u003eStainless steel header for long-term heat resistance and structural rigidity\u003c\/li\u003e\n\u003cli\u003eTitanium silencer body for exceptional heat dissipation and meaningful weight savings over the stock unit\u003c\/li\u003e\n\u003cli\u003eCarbon end cap adds race-inspired aesthetics alongside additional thermal protection\u003c\/li\u003e\n\u003cli\u003eTitanium internals engineered for maximum durability under sustained high-temperature cycling\u003c\/li\u003e\n\u003cli\u003eDB-killer and catalytic converter (CAT) included — compliant, quieter, and cleaner without sacrificing character\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eThe Pista system is Arrow's track-to-road interpretation of what a performance exhaust should be. The stainless steel header section flows gases more efficiently than the factory unit, feeding into the titanium silencer where the internal geometry has been shaped to sharpen throttle pickup and broaden the usable power band. The result is a system that rewards both smooth road riding and hard track sessions equally.\u003c\/p\u003e\u003cp\u003eArrow's use of titanium for both the silencer shell and internal components is deliberate: the material runs cooler under load, resists corrosion without coatings, and saves weight where it matters most — high and rearward on the chassis. The carbon end cap is not merely decorative; it insulates the terminal heat point and reinforces the outlet under racing conditions.\u003c\/p\u003e\u003ch2\u003eRoad Use \u0026amp; Compliance\u003c\/h2\u003e\u003cp\u003eDespite its track-derived name, the Pista system is fully street-legal. The included DB-killer reduces sound output to compliant levels, while the integrated catalytic converter keeps emissions within current road regulations. The E-approval number means fitting this system does not invalidate your insurance or require any modification to your registration documents.\u003c\/p\u003e\u003cp\u003eFor riders who want to maximise the performance gain, Arrow recommends a custom ECU mapping to optimise fuelling in line with the freer-flowing exhaust. While the system delivers a noticeable improvement on the standard map, dedicated mapping will unlock its full potential.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis complete exhaust system is designed and manufactured as a direct, no-modification fit for the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R7 — model years 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eInlet diameter: 54 mm.
