Arrow Race-Tech Carbon Slip-On Silencer – Aprilia RSV4 1100 Factory (2019-2020) 71906MK

Arrow's Race-Tech series represents the Italian manufacturer's purest expression of motorsport craft brought to road-legal homologation. The 71906MK slip-on silencer for the Aprilia RSV4 1100 Factory pairs a full carbon fibre canister with a carbon end-cap, creating a finish that is as visually striking as it is purposeful — the kind of exhaust note and aesthetic that reflects the RSV4's superbike lineage without compromise.

Key Features

• Full carbon fibre silencer body with matching carbon end-cap for a cohesive, race-bred appearance and significant weight reduction over the OEM unit.
• Stainless steel internals provide long-term corrosion resistance and structural integrity under sustained high-temperature cycling.
• E-number road homologation: fully legal for road use straight from the box.
• Removable dB-killer included, allowing the silencer to transition between road-compliant and open track configurations with minimal effort.
• Plug-and-play fitment designed specifically for the RSV4 1100 Factory — no cutting, welding or fabrication required.
• Compatible with Arrow mid-pipes to form a complete performance exhaust system for measurably improved throttle response and power delivery.

Design, Finish and Heritage

Arrow has been crafting exhaust systems in Calderara di Reno, Italy, since 1969, and the Race-Tech line distils decades of competition experience into road-legal hardware. The 71906MK canister uses high-grade woven carbon fibre across the full outer shell — not a carbon-look wrap or partial sleeve — giving the silencer the same visual language as the components found on factory Superbike machinery. The carbon end-cap continues that theme cleanly, avoiding the mismatched aesthetics that plague lesser aftermarket fitments.

At 2.43 kg the canister is appreciably lighter than the original equipment exhaust, contributing to a reduction in unsprung and high-mounted mass that sharpens the RSV4's already razor-edged handling. The stainless steel internal baffle assembly ensures the carbon shell is never under structural stress, and the removable dB-killer means the silencer can be configured for a Sunday morning road ride or a track day without reaching for tools.

Performance and System Compatibility

As a slip-on, the 71906MK delivers an immediate improvement in exhaust note character and a modest gain in mid-to-upper-range breathing. To unlock the full performance potential — optimised throttle response, improved mid-range torque and peak power gains — the silencer should be paired with a compatible Arrow mid-pipe to create a complete exhaust system. If you already run an Arrow link pipe, this canister connects directly without further modification. For best results, a custom ECU mapping or Arrow-recommended fuel map is advised after installation.
