• Arrow 11001EM A.R.D. – removes the engine fault message (the catalog specifically indicates it for these two motorcycles)

The db-killer 11021DB is another code in the Arrow catalog for these motorcycles: contact us if you need it and we will order it.

Who is it perfect for?

It's the system for those who take their RS 660 or Tuono 660 to the track, want to replace the entire exhaust, and prefer the dark aesthetic over exposed titanium: the matte black aluminum with the carbon end cap pairs well with the more understated color schemes of the bike, and the kit costs less than the titanium version. Those who need to remain street legal should not install it.

Frequently Asked Questions

Is the Arrow 77008AKN kit homologated?
No. Arrow classifies it as a Racing product: it does not have ECE homologation and cannot be used on public roads. By installing it, the motorcycle is no longer compliant for road circulation or inspection, so it should only be used on track or closed circuits.

Which motorcycles does it fit?
The Arrow catalog dedicates it to two motorcycles: the 2025-2026 Aprilia RS 660, vehicle type XG, and the Aprilia Tuono 660 from the same biennium, vehicle type XH. Both are Euro 5+ with dual lambda sensors, and it's the exact same code for both.

What is the difference from the 77008PK?
It's the same complete kit, with the same design and the same stainless steel headers. The material of the silencer body changes: aluminum with a matte black Dark finish on the 77008AKN, exposed titanium on the 77008PK. The end cap is carbon on both, and the Dark version is lower priced.

Is the db-killer included?
No. The Arrow technical sheet indicates that the db-killer is not present on this kit: it is provided as a separate accessory with code 11021DB, dedicated to Indy Race EVO silencers. It must therefore be purchased separately if you need it to comply with a circuit's sound limits.

Do I need to remap?
Yes. The Arrow catalog explicitly states that installing a complete kit requires loading the racing map by contacting an Aprilia dealer. Without it, the system will not operate in the configuration for which it was designed.

Will the engine fault light come on?
It can happen: both motorcycles have two lambda sensors, and the Arrow catalog warns that installing a racing exhaust may trigger the "engine fault" message. In that case, the A.R.D. 11001EM device is used, which suppresses the notification without affecting the mapping.
