The 250 mm aluminium canister is compact enough to keep tight cornering clearance on the R3's chassis, while the matched 45 mm inlet and outlet diameters maintain exhaust gas velocity for a broad, usable power delivery rather than a narrow peak that only appears at the top of the rev range. The dark aluminium finish is far more forgiving than polished stainless in everyday conditions — road grime and water spots simply do not show, keeping the bike looking sharp between washes.\u003c\/p\u003e\u003ch2\u003eMaterials and Construction\u003c\/h2\u003e\u003cp\u003eArrow selects dark anodised aluminium for the outer sleeve because it strikes the best balance between weight, thermal performance and durability for street-focused applications. The carbon fibre end cap is not merely cosmetic; it insulates the outlet area and shaves grams from a region that benefits most from low mass. Internal baffling and packing use stainless steel throughout, ensuring corrosion resistance and consistent sound output over the life of the silencer. The DB-Killer slots into the outlet and can be removed for closed-circuit use in minutes.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis silencer is a direct bolt-on replacement for the standard exhaust on the following model:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eYamaha YZF-R3 — model years 2015, 2016, 2017 and 2018\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003ePlease note: the primary product image is a representative render as Arrow had not yet produced a model-specific photograph for the YZF-R3 at the time of listing.
