Arrow Race-Tech Slip-On Silencer Aluminium Dark – Aprilia RSV4/RR/RF (2015-2016) 71744AKN

The Arrow Race-Tech slip-on silencer 71744AKN carries an E-number road-use approval, meaning it meets European type-approval standards straight out of the box — no legal grey areas, no track-only compromise. Developed specifically for the Aprilia RSV4, RSV4 RR and RSV4 RF (model years 2015-2016), it pairs a dark anodised aluminium canister with a carbon end cap to deliver a genuinely purposeful upgrade that is as compliant on the road as it is aggressive on the track.

Key Features

• E-number certified for full road legality across Europe — no de-cat paperwork headaches.
• Dark anodised aluminium canister keeps weight to just 2.43 kg, reducing unsprung and overall mass for sharper, more responsive handling.
• Carbon end cap adds a motorsport aesthetic while withstanding sustained exhaust temperatures without fading or cracking.
• Stainless steel internals resist corrosion and fatigue, protecting the silencer's sound and performance characteristics over thousands of kilometres.
• Removable dB killer included — run it compliant on the road, pull it for track days when regulations allow.
• Plug-and-play fitment onto a compatible Arrow link pipe; pairs with an Arrow mid-pipe to form a full race system for maximum power gains.

Construction and Performance

Arrow's Race-Tech series occupies the sweet spot between homologated road use and genuine performance engineering. The 71744AKN canister is built around stainless steel baffling contained within a dark anodised aluminium outer shell — a material pairing that sheds weight aggressively while maintaining the structural rigidity needed to survive track abuse. The 60 mm inlet and 50 mm outlet dimensions are optimised for the RSV4 platform's exhaust gas flow at race-derived throttle openings, broadening the mid-range and sharpening throttle response without the paperwork burden of a track-only system.

The carbon end cap is not a cosmetic afterthought. Arrow sources it as a heat-management component as much as a styling element, channelling and dispersing exhaust gases cleanly at the exit point. Combined with the removable dB killer, this silencer adapts to your riding environment rather than forcing a compromise.

Road and Track Use

The E-number approval means this silencer is legal for everyday road use in all European markets without additional documentation. For track use, removing the dB killer — a straightforward, tool-assisted process — opens the exhaust note further and can liberate additional top-end performance. Arrow recommends a dedicated ECU remap when running the silencer as part of a full system with an Arrow link pipe; this is particularly important on the RSV4's ride-by-wire fuelling system, where a tailored map transforms throttle response and exploits the freer-flowing exhaust to its full potential.

Fitment and Compatibility

This slip-on silencer is designed exclusively for use with a compatible Arrow link pipe — it cannot be fitted directly to the stock headers. If you already own an Arrow mid-pipe for the RSV4 platform, the 71744AKN bolts straight on to complete a full Arrow exhaust system.
