dB killers

dB killers are used to reduce the noise level from the exhaust. They are typically mounted at the end of the rear silencer or tailpipe and function as a noise-reducing insert that dampens the sound from the exhaust system. This makes them relevant for sports exhausts, motorcycles, custom-built exhaust systems, race cars and trackday cars where the noise level needs to be reduced.

In this category, you will find dB killers, silencer inserts and exhaust inserts in different sizes and designs. They are typically used when an exhaust is too loud, when the noise level needs to be adjusted to track or event requirements, or when a more subdued sound from a sports exhaust is desired.

When choosing a dB killer, it is important to check diameter, length, mounting method and whether the insert fits the exhaust tailpipe or rear silencer. A correctly mounted dB killer can reduce noise without requiring replacement of the entire exhaust system, but it can also affect flow, back pressure and sound character depending on the construction of the exhaust.
