Arrow Race-Tech Carbon Slip-On Silencer – Aprilia RSV4 / RR / RF (2015-2016) 71744MK

Arrow's Race-Tech series represents the Italian brand's commitment to genuine motorsport provenance brought to the road, and the 71744MK is one of its most visually striking expressions. Crafted with a carbon canister and matching carbon end caps, this slip-on silencer is purpose-built for the Aprilia RSV4, RSV4 RR and RSV4 RF (2015–2016), delivering a weight of just 2.23 kg alongside an aesthetic that belongs on a Superbike grid as much as on the open road.

Key Features

• Genuine carbon canister and carbon end caps for a unified, race-derived finish that complements the RSV4's aggressive styling.
• Stainless steel internals ensure long-term structural integrity and full resistance to heat and corrosion.
• Weighs only 2.23 kg — a meaningful reduction over the standard silencer that contributes to sharper handling and improved mass centralisation.
• E-number road approval included, making this a fully legal fitment for everyday road use.
• Removable dB killer allows the exhaust note to be adjusted between civilised road manners and a more vocal track character.
• Compatible with an Arrow mid-pipe to form a complete, performance-optimised exhaust system capable of tangible gains in power and throttle response.
• Plug-and-play installation — drops straight onto the stock or Arrow mid-pipe without modification.

Design, Finish and Heritage

Arrow has been supplying exhaust systems to World Superbike teams for decades, and the Race-Tech range channels that experience directly into a road-legal product. The carbon weave on the 71744MK is not a cosmetic film — the canister is constructed from genuine carbon fibre, keeping weight low and heat tolerance high. The carbon end caps continue the visual theme without interruption, creating a single coherent surface that elevates the RSV4's tail section from factory-spec to something altogether more purposeful.

That heritage matters because it shapes every design decision: the stainless steel internals resist the sustained high exhaust temperatures that a V4 engine produces, while the overall geometry is optimised for the specific pipe routing of the 2015–2016 RSV4 platform.

Performance and Road Use

Fitted as a standalone slip-on, the Race-Tech delivers an improved exhaust note and a modest weight saving. Paired with a compatible Arrow mid-pipe, the system becomes a full performance exhaust, and Arrow recommends a dedicated ECU mapping in this configuration to unlock the full gains in power delivery and throttle response. The removable dB killer means the same silencer serves both a noise-sensitive morning commute and an unrestricted track day without any permanent alteration to the unit.

Fitment and Compatibility

This silencer fits the following models:

• Aprilia RSV4 (2015–2016)
• Aprilia RSV4 RR (2015–2016)
• Aprilia RSV4 RF (2015–2016)

The slip-on requires a compatible Arrow mid-pipe — it is not designed to mate directly with the standard header system. If you already own an Arrow mid-pipe for this platform, the 71744MK completes the system immediately.
