Who is this for?

It is the right part for those who have installed an Arrow Indy Race EVO racing system and want to lower the noise level when necessary – in the city, at home, or on tracks with noise restrictions – without sacrificing the exhaust's full sound when removed. It is also for those who have lost or damaged their supplied dB-Killer and are looking for the exact replacement.

Frequently Asked Questions

What is the Arrow 11020DB dB-Killer used for?
It is an internal silencer that inserts into the outlet of the Arrow Indy Race EVO muffler to reduce its sound level. It is called "removable" because it can be installed and uninstalled as desired; inside the tube, it acts as a restrictor that slows down and cools the exhaust gases.

Which motorcycles does it fit?
Seven applications: 2025-2026 Yamaha MT-07, 2024-2026 MT-09 and MT-09 SP (including the 35 kW restricted version), 2025-2026 Tracer 9 (all versions), 2025-2026 YZF R9, and 2024-2026 Honda CB 650 R and CBR 650 R. These are the seven assembly diagrams where the Arrow catalog lists this code.

Does my racing kit already have one?
No. For all seven applications, the complete Indy Race EVO racing kit is listed in the catalog without a dB-Killer, so it must be purchased separately. Single mufflers for the MT-07 and YZF R9 and the homologated kits for the CB 650 R, CBR 650 R, and YZF R9 include it as standard; in those cases, the 11020DB is a replacement part.

What are its measurements?
The only dimension Arrow publishes for this item is the 32 mm diameter, which appears in the part name. Body length, insertion diameter, and outlet diameter are not declared by the manufacturer, so we do not provide them.

What material is it made of, and how much does it weigh?
Arrow does not declare the material for this part number; the table lists it generally as "Metal" rather than a specific alloy. The weight is also not published: the 0.2 kg figure is an estimate based on other dB-Killers in the same family where Arrow does provide the weight.

Is it an original Arrow product?
Yes. It is an official Arrow Special Parts catalog item with code 11020DB and EAN 8030656100986, brand new and produced in Italy. Moon Bike S.r.l., based in Cercola (Naples), ships from Italy with an invoice and a 2-year warranty.
