DescriptionThe whole story▼
The Arrow 71542GPI GP2 Dark slip-on silencer is constructed entirely from high-grade stainless steel — body, end cap and internal components alike — delivering a standard of corrosion resistance and heat tolerance that sets it apart from budget alternatives. At just 1.49 kg, it trims meaningful mass from the tail of the Aprilia RSV4, RR and RF (2017-2018) while projecting the compact, race-derived GP2 silhouette that the platform deserves.
Key Features
- Full stainless steel construction throughout: outer canister, end cap and internals — resistant to extreme heat, vibration and weathering.
- Ultralight at 1.49 kg, reducing unsprung and rear mass for sharper handling response.
- E-number road approval included — fully legal for public road use straight out of the box.
- Removable dB killer allows you to run open on track and compliant on the road without tools.
- Plug-and-play fitment engineered specifically for the 2017-2018 RSV4 / RR / RF — no cutting, no fabrication.
- 60 mm inlet / 58 mm outlet diameter with a 200 mm overall canister length for precise header integration.
Build Quality and Materials
Arrow has long been synonymous with Italian craftsmanship, and the GP2 Dark range reflects that heritage at every weld. The stainless steel canister resists the discolouration and surface degradation that afflict mild-steel or aluminised equivalents over time. Internal baffling is likewise stainless, maintaining structural integrity under prolonged high-RPM use on both road and track. The end cap maintains the same material spec as the body, giving the silencer a unified, purposeful finish rather than the mismatched look of cheaper mixed-material units.
Performance and Road Use
The GP2 geometry is compact and purposeful, positioning mass close to the bike's centre rather than cantilevered at the tail — a measurable benefit when the RSV4 is being worked hard through direction changes. The removable dB killer gives genuine dual-purpose flexibility: fitted for commuting or touring, removed for a track day where noise regulations are less restrictive. Arrow strongly recommends pairing this slip-on with a dedicated ECU remap to realise the full gains in throttle response and top-end output.
