Drawing on Arrow's decades of grand prix and Superbike heritage, this system pairs a stainless steel header with a titanium silencer and carbon end-cap — a combination that defines the Competition range's signature look and uncompromising track focus. The result is a complete exhaust that reduces mass, sharpens power delivery and carries the unmistakable aesthetic of Italian race craft.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFull system design — header and silencer developed together for optimised flow and power gains across the rev range\u003c\/li\u003e\n\u003cli\u003eStainless steel header construction for lasting corrosion resistance and structural integrity under sustained race use\u003c\/li\u003e\n\u003cli\u003eTitanium silencer body delivers meaningful weight savings while projecting the Competition range's distinctive raw finish\u003c\/li\u003e\n\u003cli\u003eCarbon fibre end-cap — heat-resistant, lightweight and a defining visual detail that sets this system apart\u003c\/li\u003e\n\u003cli\u003eStainless steel silencer internals for durability and consistent acoustic performance over time\u003c\/li\u003e\n\u003cli\u003eRemovable dB-killer included, allowing the system to run open on track or compliant for paddock noise limits\u003c\/li\u003e\n\u003cli\u003eA dedicated ECU mapping remap is recommended to realise the full performance benefit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eArrow has supplied exhaust systems to factory race teams and championship-winning riders for over forty years. The Competition series inherits that DNA directly: every joint, cone and collector is designed in-house and manufactured in Italy to the same tolerances Arrow applies to their OEM motorsport contracts. The three-material construction — stainless, titanium, carbon — is not a styling exercise. Each material is selected for the specific thermal and structural demands of its position in the system, and together they give the RC 390 a visual signature that is immediately recognisable in the paddock.\u003c\/p\u003e\u003cp\u003eThe stainless steel header resists the extreme heat cycles produced by the RC 390's high-revving single-cylinder engine, while the titanium silencer absorbs and dissipates that heat further downstream without the weight penalty of steel. The carbon end-cap caps the system cleanly, providing a heat shield and a premium finish in one piece.\u003c\/p\u003e\u003ch2\u003ePerformance and Track Use\u003c\/h2\u003e\u003cp\u003eThis system is rated for race use only and is not road-legal. With a total system weight of 6.5 kg and carefully matched inlet and outlet diameters, it is designed to reduce back-pressure and improve scavenging on the RC 390's single-cylinder engine. Arrow recommends a dedicated ECU remap to take full advantage of the revised exhaust flow — without remapping, some of the potential power and torque gains will remain unrealised. The removable dB-killer gives riders the flexibility to meet circuit noise limits without compromising the open-system character when regulations allow.\u003c\/p\u003e\u003ch2\u003eFitment and Compatibility\u003c\/h2\u003e\u003cp\u003eThis complete exhaust system is designed and tested specifically for the following motorcycle:\u003c\/p\u003e\u003cul\u003e\u003cli\u003eKTM RC 390 — model years 2022, 2023, 2024 and 2025\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003ePart number: 71229PTZ.
