Arrow Pro-Race Slip-On Silencer Kit Stainless Steel – Aprilia RSV4/RR/RF (2017-2018) 71214PRI

Shed weight without sacrificing durability: the Arrow Pro-Race slip-on silencer 71214PRI is a straightforward, cost-effective upgrade for the Aprilia RSV4, RSV4 RR and RSV4 RF (2017-2018) that delivers a measurable reduction in unsprung mass alongside Arrow's characteristically crisp exhaust note. Built entirely from stainless steel — canister, end cap and internals alike — it is engineered to withstand the sustained heat cycles of repeated track sessions while remaining a practical bolt-on for riders who want more from their machine without a full system overhaul.

Key Features

• Full stainless steel construction throughout: canister body, end cap and internal components — corrosion-resistant and thermally stable session after session.
• Weighs just 1.93 kg, delivering a genuine reduction in overall bike weight for improved handling and agility.
• Removable dB killer included — run it for noise compliance at test day venues, remove it when regulations allow.
• Plug-and-play fitment designed specifically for the Aprilia RSV4/RR/RF 2017-2018 — no cutting or fabrication required.
• Compact Pro-Race canister profile keeps mass centralised and clears bodywork cleanly.
• Race-use only product — no road homologation required, so no compromises made for street legislation.

Build Quality and Performance

Arrow manufactures the 71214PRI with a 60 mm inlet diameter and a 68 mm outlet, dimensions that preserve exhaust gas velocity through the collector transition and into the canister. The 200 mm overall canister length keeps the unit tight to the subframe, avoiding leverage forces on the collector joint during hard cornering. Stainless steel internals resist the packing degradation common in budget exhausts, meaning the tone and flow characteristics remain consistent across a full season of track use.

For riders looking to extract the maximum from the combination, Arrow and Aprilia both recommend a dedicated ECU map tuned to the open exhaust. Throttle response across the mid-range in particular benefits noticeably from a remapped fuelling strategy, and a specialist dyno session will confirm the gains available from the RSV4's V4 architecture when properly fuelled.

Fitment and Compatibility

This slip-on kit is designed exclusively for the following models:

• Aprilia RSV4 (2017-2018)
