Weighing in at just 0.85 kg, this mid-pipe strips unnecessary mass from the RSV4's drivetrain package while laying the groundwork for serious track performance.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePrecision-crafted from high-grade stainless steel for lasting corrosion resistance and structural integrity under sustained race conditions\u003c\/li\u003e\n\u003cli\u003eUltralight at 0.85 kg — a direct, measurable contribution to the RSV4's power-to-weight ratio\u003c\/li\u003e\n\u003cli\u003eUniform 60 mm inlet and outlet diameter for smooth, unrestricted gas flow between the OEM header and Arrow slip-on silencer\u003c\/li\u003e\n\u003cli\u003ePlug-and-play fitment onto the original Aprilia header — no cutting, drilling or custom fabrication required\u003c\/li\u003e\n\u003cli\u003eDesigned in conjunction with Arrow's slip-on silencer range to form a complete, performance-optimised exhaust system\u003c\/li\u003e\n\u003cli\u003eRace-use component, purpose-built for track environments where every gram and every horsepower counts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eArrow has been shaping exhaust systems for the world's fastest production motorcycles since the 1970s, and the 71674MI carries that heritage in every weld. The natural stainless finish is left to develop its own patina under race heat — a hallmark of Italian craftsmanship that prioritises function without sacrificing aesthetics. The precise tube geometry reflects the same computational fluid-dynamics thinking Arrow applies to its WorldSBK and MotoGP development work, ensuring the RSV4's V4 character comes through clean and unobstructed.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003ePaired with a compatible Arrow slip-on silencer, the 71674MI transforms a standard RSV4 exhaust into a proper race assembly. Improved gas scavenging sharpens throttle response across the rev range, and the reduction in unsprung and reciprocating mass translates directly into more agile, predictable handling on circuit. To extract the full potential of the system, a remap or ECU reprogramming is strongly recommended — a worthwhile investment that unlocks the true performance gains available from the combination.\u003c\/p\u003e\u003cp\u003eNote: this mid-pipe is designed for use with the original Aprilia header only and requires a matching Arrow slip-on silencer to complete the assembly.
