Weighing just 1.43 kg and finished in stainless dark, it delivers sharper throttle response and a more purposeful exhaust note while keeping the RC 390 fully road-legal thanks to its included E-number homologation and removable dB killer.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eWeighs only 1.43 kg — a meaningful reduction over the stock silencer that improves handling balance without any trade-off in durability.\u003c\/li\u003e\n\u003cli\u003eFull stainless steel construction throughout — body, end cap and internals — resists corrosion and high operating temperatures season after season.\u003c\/li\u003e\n\u003cli\u003eStainless Dark end cap finish: the darkened heat-treated look adds a purposeful, understated aesthetic that suits the RC 390's aggressive lines.\u003c\/li\u003e\n\u003cli\u003eSupplied with a removable dB killer so you can run it quietly on the road or open it up on track days without buying separate accessories.\u003c\/li\u003e\n\u003cli\u003eE-number road approval included — no MOT headaches, no need to swap exhausts before a ride.\u003c\/li\u003e\n\u003cli\u003eCompatible with the original KTM header or any Arrow header, making it an easy bolt-on with no additional bracketry required.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePerformance \u0026amp; Build Quality\u003c\/h2\u003e\u003cp\u003eArrow engineered the Pro-Race range to bridge the gap between a purely street silencer and a dedicated race can. The 250 mm body length and 68 mm outlet diameter are sized specifically for the RC 390's engine characteristics, promoting mid-range responsiveness that makes the most of the single-cylinder's torque. Stainless steel internals handle the sustained heat cycles that smaller-displacement engines generate at high revs, and the overall construction is consistent with Arrow's reputation for Italian precision manufacturing.\u003c\/p\u003e\u003cp\u003eFor riders looking to extract every last gain, Arrow recommends a custom ECU map to complement the freer-flowing exhaust. While the silencer delivers a noticeable improvement over stock even without remapping, a tailored fuel map will sharpen throttle response further and ensure the fuelling remains clean across the rev range.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThis slip-on is designed exclusively for the KTM RC 390 covering model years 2017 to 2020. It connects directly to the standard KTM header pipe or to any Arrow mid-pipe for the same application.
