Arrow Race-Tech Aluminium Dark Slip-On Silencer Aprilia RSV4 1100 Factory (2019-2020) 71906AKN

Road-legal and race-ready, the Arrow 71906AKN Race-Tech slip-on silencer carries a full E-number homologation — meaning it passes European street-use certification straight out of the box and can be ridden on public roads without compromise. Developed specifically for the Aprilia RSV4 1100 Factory in model years 2019 and 2020, it pairs a dark anodised aluminium canister with a carbon end cap for a finish that looks as purposeful as it performs.

Key Features

• E-number road homologation: fully certified for public road use across Europe, with no grey areas on legality.
• Dark anodised aluminium canister: corrosion-resistant, weight-saving construction with an aggressive, race-derived aesthetic.
• Carbon end cap: adds rigidity and a premium look, keeping weight to a minimum at 2.43 kg total.
• Stainless steel internals: resist heat and corrosion over tens of thousands of kilometres.
• Removable dB killer: tames noise for road use or commuting; pull it out when you want the full Race-Tech soundtrack on track.
• Plug-and-play fitment: bolts directly to the stock mid-pipe or, for full-system performance gains, pairs with an Arrow mid-pipe to complete the exhaust package.

Performance & Build Quality

At 2.43 kg the 71906AKN is a meaningful weight reduction over the factory exhaust unit, lowering unsprung and overall mass to sharpen the RSV4 1100 Factory's already exceptional handling. The 60 mm inlet and 50 mm outlet dimensions are tuned to the engine's exhaust gas velocity at racing revs, giving a noticeable improvement in throttle response and mid-to-top-end power delivery compared with the stock silencer.

The combination of a dark-finish aluminium outer shell and stainless steel internals is a deliberate choice: aluminium sheds heat quickly and resists the oxidising effects of UV and road spray, while stainless steel baffles maintain their geometry and sealing integrity across extreme temperature cycles. The carbon end cap completes the heat management picture, insulating the outlet area and providing a visually striking contrast against the dark canister.

Expanding to a Full System

The 71906AKN is designed to work in conjunction with an Arrow mid-pipe. If you already own a compatible Arrow link pipe, the transition to a complete system is entirely bolt-on. Running the slip-on as part of a full Arrow system unlocks the greatest performance gains; Arrow recommend a custom ECU mapping at that point to fully exploit the improved airflow and extract every horsepower the RSV4 1100 Factory's V4 engine is capable of producing.

Fitment & Compatibility

• Aprilia RSV4 1100 Factory — 2019
• Aprilia RSV4 1100 Factory — 2020

Requires an Arrow mid-pipe for installation. Not compatible with the standard OEM mid-pipe as a standalone replacement. Please verify fitment against your specific build date before ordering.
