Who is it for?

This is the part needed for those who have already installed an Arrow Pro-Race terminal and want to reduce noise when a track day requires it, or for those who have lost or damaged the included dB-Killer and need to replace it with the original. It applies to the CFMOTO 675 NK and CFMOTO 675 SR-R (2025-2026), the Honda CB 650 R and Honda CBR 650 R (2019-2023), the Honda CBR 1000 RR-R (2024-2026), and the Suzuki GSX-R 1000 and GSX-R 1000 R (2017-2020). Those who use their motorcycle only on the street must remember that the part remains classified as racing.

Frequently Asked Questions

Which motorcycles does the Arrow 11012DB dB-Killer fit?
The official Arrow Special Parts catalog lists it for the CFMOTO 675 NK and 675 SR-R (2025-2026), Honda CB 650 R and CBR 650 R (2019-2023), Honda CBR 1000 RR-R (2024-2026), and Suzuki GSX-R 1000 and 1000 R (2017-2020).

Which Arrow terminals can it be used with?
The 11012DB is the dB-Killer for the Pro-Race line: it fits into the ø68 mm outlet of titanium and nichrom Pro-Race terminals, such as codes 71217PR, 71207PR, and 71225PR. Other Arrow lines, such as Indy Race EVO or Thunder, require a dB-Killer with a different code.

Is it homologated for road use?
No. In the official Arrow Special Parts catalog, the 11012DB code is classified as racing, meaning it is non-homologated, for all six applications. It must be used on a track or in a closed circuit. It reduces the noise of the Pro-Race terminal, but it does not make a non-homologated exhaust road-legal.

What material is it made of and what are its dimensions?
The body is steel with a natural silver-colored finish and visible welding. The inlet that rests on the terminal outlet measures ø68 mm, while the internal gas passage pipe is ø35 mm. The weight declared by Arrow Special Parts is 0.2 kg.

How many pieces are needed for a motorcycle?
One is needed for each Pro-Race terminal installed on the motorcycle: a single terminal requires one piece, while a dual-terminal system requires two. The price shown on this page refers to a single dB-Killer, not a pair.

How can I be sure it is the right one for my exhaust?
Check the code printed on the terminal: if it is an Arrow from the Pro-Race line with a ø68 mm outlet, the 11012DB is the correct spare part. If in doubt, send us the terminal code and the motorcycle model with the year, and we will verify compatibility.
