The silencer body is formed from stainless steel with a dark finish that resists heat and corrosion while projecting an unmistakably aggressive track aesthetic — a material choice that sets it apart from entry-level titanium or carbon alternatives where longevity under repeated racing stress is the priority.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull stainless steel construction throughout — canister, end caps and internals — delivering exceptional heat resistance and long-term durability under sustained race conditions.\u003c\/li\u003e\n\u003cli\u003eUltra-light at just 1.63 kg, offering a meaningful reduction in unsprung and overall weight compared to the standard exhaust assembly.\u003c\/li\u003e\n\u003cli\u003eCompact Pro-Race canister geometry contributes to improved ground clearance and a purposeful, race-bred silhouette.\u003c\/li\u003e\n\u003cli\u003eRemovable dB killer included, allowing noise management during paddock sessions without compromising full-power performance when conditions permit.\u003c\/li\u003e\n\u003cli\u003ePlug-and-play fitment designed specifically for the 2017–2018 RSV4 platform — no fabrication or modification required for installation.\u003c\/li\u003e\n\u003cli\u003eFor optimal throttle response and power delivery, a dedicated ECU mapping is recommended alongside installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eMaterials and Build Quality\u003c\/h2\u003e\u003cp\u003eWhere many slip-on silencers in this class use mixed materials to cut costs, the 71214PRN is built entirely from stainless steel. The canister itself carries Arrow's dark treatment for a subdued, purposeful look; the end caps share the same stainless specification, ensuring a cohesive finish rather than the visual mismatch that can come with composite end treatments. Internally, stainless steel components provide consistent flow characteristics and structural integrity even under the thermal cycling that race use demands.\u003c\/p\u003e\u003cp\u003eThe 200 mm overall length keeps the package compact, while the 60 mm inlet and 68 mm outlet dimensions are matched precisely to the RSV4's header system, ensuring gas flow is never compromised by fitment tolerances.\u003c\/p\u003e\u003ch2\u003eTrack Performance\u003c\/h2\u003e\u003cp\u003eThe Pro-Race designation is not a marketing label — this silencer carries no road homologation and is intended solely for closed-circuit competition and track-day use. That single-purpose focus allows Arrow to optimise the internal geometry for peak power across the RSV4's rev range without the acoustic or emissions compromises that street-legal units require. Pair it with a custom remap to unlock the full benefit of the freer-flowing exhaust path.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAprilia RSV4 (2017–2018)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RR (2017–2018)\u003c\/li\u003e\n\u003cli\u003eAprilia RSV4 RF (2017–2018)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eDirect bolt-on replacement for the stock slip-on section.
