On the vehicle registration and on the RDW website, it is stated exactly how much noise your exhaust is allowed to produce according to the law. Measuring this accurately can be difficult and requires a decibel meter.

We indicate on our website for each product whether the decibel killer is removable. Manufacturers are required to provide EURO4 and EURO5 exhausts without removable DB-Killer.

Motorcycles from 2016 must comply with the EURO4 standard.

Motorcycles from 2021 must comply with the EURO5 standard.

For motorcycles up to the year of manufacture 2015, it is not mandatory to have a fixed killer. Manufacturers determine themselves whether they make the killer removable or not.

This is described in detail on the relevant product page in our webshop.

You will receive a card or certificate with proof of approval for each approved exhaust system. The approval mark is also stamped on the exhaust.
