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

Arrow's Pro-Race slip-on kit 71214PRN is engineered from the ground up for the Aprilia RSV4, RR and RF (2017–2018), and it shows in every detail of its construction. The silencer body is formed from stainless steel with a dark finish that resists heat and corrosion while projecting an unmistakably aggressive track aesthetic — a material choice that sets it apart from entry-level titanium or carbon alternatives where longevity under repeated racing stress is the priority.

Key Features

• Full stainless steel construction throughout — canister, end caps and internals — delivering exceptional heat resistance and long-term durability under sustained race conditions.
• Ultra-light at just 1.63 kg, offering a meaningful reduction in unsprung and overall weight compared to the standard exhaust assembly.
• Compact Pro-Race canister geometry contributes to improved ground clearance and a purposeful, race-bred silhouette.
• Removable dB killer included, allowing noise management during paddock sessions without compromising full-power performance when conditions permit.
• Plug-and-play fitment designed specifically for the 2017–2018 RSV4 platform — no fabrication or modification required for installation.
• For optimal throttle response and power delivery, a dedicated ECU mapping is recommended alongside installation.

Materials and Build Quality

Where many slip-on silencers in this class use mixed materials to cut costs, the 71214PRN is built entirely from stainless steel. The canister itself carries Arrow's dark treatment for a subdued, purposeful look; the end caps share the same stainless specification, ensuring a cohesive finish rather than the visual mismatch that can come with composite end treatments. Internally, stainless steel components provide consistent flow characteristics and structural integrity even under the thermal cycling that race use demands.

The 200 mm overall length keeps the package compact, while the 60 mm inlet and 68 mm outlet dimensions are matched precisely to the RSV4's header system, ensuring gas flow is never compromised by fitment tolerances.

Track Performance

The Pro-Race designation is not a marketing label — this silencer carries no road homologation and is intended solely for closed-circuit competition and track-day use. That single-purpose focus allows Arrow to optimise the internal geometry for peak power across the RSV4's rev range without the acoustic or emissions compromises that street-legal units require. Pair it with a custom remap to unlock the full benefit of the freer-flowing exhaust path.

Fitment and Compatibility

• Aprilia RSV4 (2017–2018)
• Aprilia RSV4 RR (2017–2018)
• Aprilia RSV4 RF (2017–2018)

Direct bolt-on replacement for the stock slip-on section. No modification to the existing header or link pipe required for correct fitment on the above model years.
