The Arrow 71755KZ catalytic collector kit is the front half of the Arrow exhaust system for Aprilia RS 660 (2020-2024) and Tuono 660 (2021-2024): stainless steel collectors with an integrated catalytic converter, ECE approved. This version allows you to mount an Arrow silencer while remaining compliant for road use.
This is the part needed to mount Indy Race silencers. For these two bikes, the Arrow silencers 71929PK (titanium), 71929MK (carbon), and 71929AKN (Dark aluminum) do not work with the original collectors: the Arrow catalog links them exclusively to this kit or the racing kit 71755MI. The outlet of these collectors is ø 54 mm, precisely the inlet diameter of the three silencers.
Key features
- Integrated catalytic converter and ECE approval — this version retains the catalytic converter: the Arrow system remains usable on the road and compliant for inspections.
- No remapping required — the Arrow technical note requiring the upload of the Racing map from an Aprilia dealer concerns the racing kit 71755MI, not this one.
- Stainless steel — collectors and link pipe are both made of stainless steel, with a welded bracket.
- Designed for lambda sensor — the kit retains the original lambda sensor connection of the bike.

⚠️ Important notes
This kit is the front half of the system: it does not complete the exhaust alone. It must be purchased together with one of the three Indy Race silencers, or added if the silencer is already installed.
Installation is recommended for qualified personnel. No remapping is required: that is requested by the Arrow technical note for the racing collector kit 71755MI, which is catalyst-free and intended for track use only.
Compatibility

|---|---|---|---|
| Aprilia | RS 660 — Euro 5 | 2020-2024 | KS |
| Aprilia | Tuono 660 — Euro 5 | 2021-2024 | KS |
List taken from the official Arrow spare parts catalog. The two bikes share the same vehicle type KS and the same system: the code is unique for both. The RS 660 and Tuono 660 from 2025 are Euro 5+ and use a different system.

Who is it perfect for
For those who want the complete Arrow system on their RS 660 or Tuono 660 and intend to continue using the bike on the road every day: the catalytic converter remains, the approval remains, and the ECU is not touched. This is the choice for those who do not want a track-only bike.

Frequently Asked Questions
Can I just mount these collectors and keep the original silencer?
The kit is designed as the front half of the Arrow system and has a ø 54 mm outlet intended for Indy Race silencers 71929PK, 71929MK, and 71929AKN. The Arrow catalog does not provide for pairing with the original bike's silencer: for a complete system, one of the three silencers is also needed.
Do I need to remap the bike?
No. The Arrow technical note that requires loading the Racing map by contacting an Aprilia dealer concerns the racing collector kit 71755MI, which is catalyst-free. The 71755KZ retains the catalytic converter and is approved: the ECU remains standard.
What is the difference with the 71755MI racing kit?
The 71755KZ has an integrated catalytic converter and is approved for road use; the 71755MI is without one, intended for track use only, and requires racing mapping. The racing kit is lighter — 3.2 kg versus 3.79 kg — and the difference is almost entirely due to the catalytic converter.
What material is it made of and how much does it weigh?
The collectors and link pipe are made of stainless steel, with a welded frame attachment. The complete kit weighs 3.79 kg according to Arrow data and has a ø 54 mm outlet.
Does it fit both the RS 660 and the Tuono 660?
Yes. The two bikes share the same Arrow vehicle type, KS, and the same system: the code is unique. This applies to the RS 660 from 2020 to 2024 and the Tuono 660 from 2021 to 2024, both Euro 5. From 2025, the two bikes switched to Euro 5+ and use different codes.
Is this an original Arrow product?
Yes: it is a new kit produced by Arrow Special Parts in San Giustino, Italy, and is the code provided by the official Arrow catalog for the RS 660 and Tuono 660. It is shipped from Italy with an invoice and manufacturer's warranty; it is not a copy or a universal adaptation.
