Arrow 11014DB dB-Killer ø35 mm Pista Silencer – Aprilia 457, Yamaha TMAX 560 and R7

The Arrow 11014DB dB-Killer is the silencer insert that the Arrow catalog dedicates to the Pista line exhaust: it slides into the silencer outlet and reduces noise, which is necessary for circuits that impose a decibel limit. Arrow identifies it with the ø35 mm measurement. Product code 11014DB.

✓ Strengths

• It is the catalog code for the Pista exhaust – not a universal fitment: on the TMAX 560, for example, the Indy Race EVO uses a different dB-Killer (11025DB)
• Reduces exhaust noise – designed for track days with decibel limits
• Removable and reusable – it remains a removable insert, not a permanent modification to the silencer
• Covers four applications – Aprilia RS 457 and Tuono 457, Yamaha TMAX 560 and YZF-R7 2026
• Made in Italy – produced by Arrow Special Parts in San Giustino (PG)

The list is taken from the four official pages of the Arrow catalog where this code appears. If your motorcycle is not listed, send us your VIN and your exhaust code before ordering.

Who it is perfect for

It is the right spare part for those who have installed an Arrow Pista line exhaust and ride on the track, where there is almost always a decibel limit, and for those who have lost or damaged the included dB-Killer and are looking for the correct replacement code. It is also ideal for those who want to be able to switch between the two configurations without modifying the silencer.

Frequently Asked Questions

Which exhausts does the Arrow 11014DB dB-Killer fit?
It fits Arrow Pista line exhausts. It appears on four catalog pages: Aprilia RS 457 2024-2026, Aprilia Tuono 457 2025-2026, Yamaha TMAX 560 2025-2026, and Yamaha YZF-R7 2026. If your Arrow exhaust is from a different line, the dB-Killer code will be different.

What are its measurements?
Arrow identifies it as "dB-Killer for Pista exhaust ø35mm," and ø35 mm is the only measurement they publish: in the catalog specifications table, length, inlet diameter, and outlet diameter are all zero, i.e., blank fields. For this reason, we do not provide other dimensions.

What material is it made of?
Arrow does not disclose the alloy of this insert: there is no row regarding materials in the specifications table. For this reason, the product sheet simply indicates metal, without specifying steel or otherwise.

Does it make my exhaust road-legal?
No. The dB-Killer lowers the noise level, which may be enough to stay within the sound limits of a circuit, but it does not transform a racing system into a road-legal one. For the RS 457 and YZF-R7 2026, Arrow also makes complete road-legal kits with the Pista silencer: in that case, the homologation applies to the entire certified system, not to this insert.

Is it already included when I buy the system?
In the Arrow catalog, the 11014DB has its own code and appears as a separate item on these four motorcycles' pages, not as part of the standard kit equipment. If you want to have it available for the track, it must be purchased separately.

How many pieces are needed?
One for each Pista silencer installed on the motorcycle: on these four applications, the system has only one silencer, so one piece is sufficient. The price on this page refers to a single dB-Killer.
