Arrow Competition Full Exhaust System Stainless Steel – KTM RC 390 (2022–2025) 71229PTZ

The Arrow Competition full exhaust system 71229PTZ is a purpose-built race exhaust engineered exclusively for the KTM RC 390 (2022–2025). 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.

Key Features

• Full system design — header and silencer developed together for optimised flow and power gains across the rev range
• Stainless steel header construction for lasting corrosion resistance and structural integrity under sustained race use
• Titanium silencer body delivers meaningful weight savings while projecting the Competition range's distinctive raw finish
• Carbon fibre end-cap — heat-resistant, lightweight and a defining visual detail that sets this system apart
• Stainless steel silencer internals for durability and consistent acoustic performance over time
• Removable dB-killer included, allowing the system to run open on track or compliant for paddock noise limits
• A dedicated ECU mapping remap is recommended to realise the full performance benefit

Design, Finish and Heritage

Arrow 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.

The 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.

Performance and Track Use

This 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.
