Arrow GP2 Slip-On Silencer Kit Titanium – Aprilia RSV4 / RR / RF (2017-2018) 71542GP

Built for riders who demand race-derived performance on road and track alike, the Arrow GP2 71542GP slip-on silencer transforms the Aprilia RSV4, RR and RF (2017-2018) with a full titanium construction that strips meaningful mass from the tail end and sharpens throttle response with every rev. At just 2.09 kg, it is one of the lightest bolt-on upgrades you can make to the RSV4 platform without touching the headers.

Key Features

• Full titanium silencer body, end caps and internals — exceptional heat resistance and corrosion immunity in a single ultra-light package
• Weighs only 2.09 kg, delivering a significant reduction over the stock unit for improved agility and lap times
• E-number type approval included — fully road-legal straight from the box without paperwork headaches
• Removable dB killer lets you run open sound on track and compliant noise levels on the road
• Compact GP2 race-profile canister sits flush with RSV4 bodywork, enhancing the superbike aesthetic without protruding awkwardly
• Plug-and-play fitment onto the existing mid-pipe — no cutting, welding or specialist tools required

Race-Bred Construction

Arrow's GP2 designation is not a styling exercise. The silencer is fabricated entirely from aerospace-grade titanium — body, internal baffling and end caps — giving the same material stack you find on Arrow's outright race kits. Titanium's natural heat-cycling properties mean the canister develops that sought-after golden-blue patina over time, making each unit visually unique. The internal geometry is tuned to complement the RSV4's V4 firing order, producing a broadened mid-range pulse and a crisp, authoritative exhaust note that carries cleanly through the rev range.

Road and Track Versatility

The included dB killer threads into the outlet and brings noise output within E-number road-legal limits — making track-day mornings and road commutes equally manageable with a single tool-free swap. Arrow recommends a purpose-developed ECU mapping to unlock the full performance potential; the GP2 is optimised for free-flowing exhaust gas exit, and a remap ensures fuelling and ignition timing are matched accordingly. Without remapping the unit will still fit and function, but a tailored map is the logical next step for anyone chasing best lap times.
