DescriptionThe whole story▼

The Arrow Race-Tech 71744AK slip-on silencer transforms the soundtrack and kerb presence of your Aprilia RSV4, RSV4 RR or RSV4 RF without the commitment of a full system. Engineered from lightweight aluminium with a carbon end-cap, it slots into your ride with a plug-and-play fit that makes for a long day in the saddle every bit as rewarding as a blast on the circuit — crisp throttle response, a purposeful exhaust note, and genuine road-legal credentials thanks to its E-approval and removable dB killer.

Key Features

  • Aluminium silencer body keeps weight down to just 2.43 kg, sharpening the RSV4's already agile handling
  • Carbon end-cap delivers a race-bred aesthetic that complements the Aprilia's aggressive bodywork
  • Stainless steel internals resist heat and corrosion for long-term durability under hard use
  • E-number approved — fully road-legal straight from the box, with the removable dB killer tuning the note for daily riding
  • Expandable system: pair with an Arrow mid-pipe to build a complete, free-flowing exhaust for measurable power gains
  • Plug-and-play installation — no cutting, no welding, no specialist tools required

Build Quality and Design

Arrow's Race-Tech line sits at the crossroads of street credibility and genuine track performance. The 71744AK's aluminium canister is the ideal match for the RSV4's V4 character: light enough to make a perceptible difference to unsprung mass without sacrificing the structural rigidity you need when scraping pegs. The carbon end-cap is not a cosmetic afterthought — it is heat-resistant, lightweight, and built to the same standard as components Arrow supplies to racing teams. The stainless steel internal components resist the thermal cycling that destroys cheaper silencers over time.

On the Road and on Track

The dB killer is included and fitted as standard, calibrated to keep the 71744AK compliant on public roads while still delivering a noticeably richer exhaust tone over the standard unit. Remove it for open circuit days and the RSV4 speaks in a register that matches its performance. For riders who want the full Race-Tech experience — improved mid-range response, sharper throttle pick-up and maximum weight saving — combining the 71744AK with an Arrow mid-pipe unlocks the system's full potential. A custom ECU remap is recommended when running the complete setup to ensure fuelling is optimised across the rev range.

Fitment and Compatibility

The Arrow 71744AK is developed specifically for the following models:

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

This silencer requires a compatible Arrow mid-pipe for installation and cannot be fitted directly to the original header without one. If you already run an Arrow mid-pipe, the 71744AK connects without modification.
