Who is it perfect for

It is the right spare part for those who have fitted an Arrow Pista line exhaust and ride on the track, where almost everywhere there is a decibel limit, and for those who have lost or damaged the dB-Killer and are looking for the right code spare part. It is also suitable for those who want to be able to alternate between the two configurations without touching the silencer.

Frequently asked questions

Which exhausts is the Arrow 11015DB dB-Killer fitted to?
To ø42 mm Arrow Pista line exhausts. It is compatible with four motorcycles: Yamaha MT-10 2022-2024, BMW M 1000 RR 2025-2026, BMW S 1000 RR 2025-2026 and Kawasaki ZX-6R 636 2024-2026. If your Arrow exhaust is from another line or another size, the dB-Killer code is different.

What size is it?
It is the «dB-Killer for ø42mm Pista exhaust», and ø42 mm is the only size available: length, fitting diameter and outlet diameter are not specified. For this reason, we do not report other dimensions.

What material is it made of?
The alloy of this insert is not specified: the sheet therefore simply indicates metal, without specifying steel or other.

Does it make my exhaust approved?
No. The dB-Killer reduces noise, and this may be enough to meet the noise limits of a circuit, but it does not turn a racing system into an approved system. On these motorcycles, Arrow makes the Pista exhaust in both racing and ECE approved versions: the approval is of the certified exhaust, not of this insert.

Is it already included when I buy the exhaust?
The 11015DB has its own code and is purchased separately for these four motorcycles, not as an exhaust accessory. If you want to have it available for the track, it must be purchased separately.

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