dB Killers, Inserts & Catalytic Converters

DB Killers & Inserts & Catalytic converters for the exhaust system

The DB Killers & Inserts & Catalytic converters are components installed in specific parts of the exhaust to modify gas flow and adapt its operation to the needs of the complete system. Depending on the design, they can function as noise reducers, internal inserts, catalytic converters, or spark arrestors. They are not interchangeable: each serves a specific purpose and requires a particular mounting method.

To choose the right component, first check the exhaust or muffler it is intended to work with and the reference specified by the manufacturer. It is also important to check the diameter, length, tip shape, mounting points, and retention system. A small difference in these measurements can prevent installation or cause looseness, vibration, and leaks.

How to check insert compatibility

• Identify whether you need a noise reducer, catalytic converter, spark arrestor, or another specific insert.
• Compare the measurements and mounting method with the removed part or the exhaust documentation.
• Make sure installation does not interfere with the gas outlet or other nearby components.
• After installation, check that the component is firmly secured and meets the requirements applicable to the motorcycle's intended use.
