Many questions about dB Killers have already been answered for you! 

Choosing the right product can be a challenge sometimes. You may not have the right fit or it may not work right away. Therefore we have answered the most questions from our customers on this subject. You will find all the information you need here. 

Do dB killers work? 

Yes, they really do. It is a hollow metal tube placed inside the final part of the motorcycle’s exhaust pipe. They work by limiting the sound waves coming out of the exhaust, helping to keep noise levels within a more manageable range without silencing the engine completely. 

Does removing dB killers affect the engine? 

It can, but usually just a little. Removing a dB killer may slightly impact backpressure, which can have a minor effect on how the engine runs. In most cases, the effect is insignificant, but it can vary depending on the exhaust system and engine setup. Many riders find that the change is mostly in the sound—louder without a huge change in performance. 

How much noise reduction can I expect from a dB Killer? 

You’ll generally see a reduction of around 5-10 decibels, depending on your setup. That’s enough to make a noticeable difference in noise but still keep your bike’s natural sound. 

Is a dB killer required for legal riding? 

Throughout Europe, the same law applies regarding the sound level of motorcycles, that they must meet specific noise regulations, especially in busy cities. This is a rather common requirement, so a dB killer can help bring exhaust noise within legal limits—it’s worth checking your local laws if you are unsure. The noise-related EU legislation states that the permissible sound levels for  two-wheel and three-wheel vehicles (including moped and motorcycles) range from 66dB(A) to 80dB(A). Of course, this depends on the vehicle itself, and this information can be found on the legal papers of your bike as well. 

Can I remove the dB killer from my exhaust? 

Many dB killers are designed to be removable, allowing you to adjust the noise level of your motorcycle. Currently, it is legal to ride without a dB killer if your bike’s noise emissions remain within the allowed limit. However, some European motorcycle and exhaust manufacturers have signed agreements to make dB killers harder to remove, supporting stricter noise control.
