Road-legal by design and race-bred at heart, the Arrow Race-Tech 71744AKN slip-on silencer carries an E-number type approval that keeps your Aprilia RSV4, RSV4 RR or RSV4 RF fully compliant on public roads — without compromising the aggressive character these superbikes demand. The dark-anodised aluminium body and carbon end-cap combination is not just a styling statement; every material choice is made to reduce unsprung mass, sharpen throttle response and reward the rider who refuses to compromise between street and track.
Key Features
- E-number type approval included — fully road-legal straight out of the box, with documentation to satisfy technical inspections.
- Removable dB killer lets you dial the sound level to suit road use or track days without permanent modification.
- Aluminium dark finish silencer body keeps weight to just 2.43 kg, contributing to improved handling and reduced unsprung mass.
- Carbon end-cap delivers lasting heat resistance and a purposeful aesthetic that complements the RSV4's aggressive lines.
- Stainless steel internals provide structural rigidity and long-term corrosion resistance across all riding conditions.
- Plug-and-play fitment designed specifically for the 2017-2018 RSV4 platform — no cutting, no fabrication required.
Construction and Performance
Arrow's Race-Tech series represents the brand's commitment to bringing genuine motorsport engineering to road-going machines. The 71744AKN silencer is constructed around a dark-anodised aluminium canister that measures 350 mm in overall length, with a 60 mm inlet and 50 mm outlet diameter. These dimensions are optimised for the exhaust flow characteristics of the RSV4 engine family, ensuring back-pressure remains within the range that supports strong mid-range torque alongside top-end power.
The stainless steel internal packing components resist the thermal cycling that causes lesser exhausts to degrade prematurely. Combined with the carbon end-cap — chosen for its low thermal expansion and high temperature tolerance — the 71744AKN is built to withstand extended hard use whether commuting or lapping a circuit.
Expanding to a Full System
The Race-Tech slip-on is designed to work exclusively with a compatible Arrow mid-pipe. If you already own an Arrow link pipe for the RSV4 platform, the 71744AKN slots straight in to complete a full Arrow exhaust system. That combination unlocks the full performance potential: measurably improved throttle response and meaningful power gains across the rev range. Arrow recommends a custom ECU mapping session after fitting the complete system to extract maximum performance and ensure fuelling accuracy at every throttle opening.
Fitment and Compatibility
- Aprilia RSV4 (2017-2018)
- Aprilia RSV4 RR (2017-2018)
- Aprilia RSV4 RF (2017-2018)
Note: this silencer requires a compatible Arrow mid-pipe and is not designed to connect directly to the OEM header system.
