Constructed from premium stainless steel with an integrated catalyst, it meets Euro 5 emissions standards and carries full E-type approval — so you can ride every day without compromise.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIntegrated catalyst ensures Euro 5 compliance and full E-type road approval straight out of the box.\u003c\/li\u003e\n\u003cli\u003ePremium stainless steel construction resists corrosion and retains its finish through all-season use.\u003c\/li\u003e\n\u003cli\u003eWeighing only 1.25 kg, the mid-pipe reduces unsprung mass without sacrificing durability.\u003c\/li\u003e\n\u003cli\u003eConsistent 60 mm inlet and outlet diameter for optimised flow and precise fitment.\u003c\/li\u003e\n\u003cli\u003ePlug-and-play installation onto the original Aprilia header — no cutting or fabrication required.\u003c\/li\u003e\n\u003cli\u003ePairs with any Arrow slip-on silencer to sharpen throttle response and improve overall performance.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eBuild Quality \u0026amp; Performance\u003c\/h2\u003e\u003cp\u003eArrow has refined exhaust engineering for decades at the highest levels of motorsport, and that expertise is evident in the 71674KZ. The stainless steel construction is formed to Arrow's exacting tolerances, meaning every joint seals cleanly and the pipe retains its shape and appearance through prolonged heat cycling. The integrated catalyst is not an afterthought — it is sized and positioned to maintain exhaust gas velocity, so back-pressure characteristics remain favourable even when the unit is used daily on public roads.\u003c\/p\u003e\u003cp\u003eWhen paired with an Arrow slip-on, the combination produces a meaningful improvement in throttle response and mid-range delivery. Arrow recommends an ECU remap after installation to extract the full performance benefit and ensure fuelling is optimised for the revised exhaust flow.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis mid-pipe is designed to fit the original (stock) header on the following motorcycles:\u003c\/p\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\u003eIt is exclusively compatible with Arrow slip-on silencers.
