DB Killers

DB Killers: Control the Sound of Your Exhaust

A DB killer, also known as a dB-reducer or silencer, lowers the sound level of your exhaust without noticeably affecting performance. This keeps your motorcycle street-legal and comfortable to ride, while still allowing you to enjoy a sporty sound. Ideal for those seeking a balance between experience and noise reduction.

The Function of a DB Killer

The DB killer is placed at the end of the exhaust and reduces exhaust noise by slowing down and dampening the gas flow. It helps to comply with legal noise standards and prevents excessive resonance at low RPMs. On many exhausts, it is easy to install or remove, depending on the intended use.

Benefits of a DB Killer

• Noise Reduction: Fewer dB without losing the characteristic motorcycle sound.
• Legal Compliance: Lowers the sound level to permissible values for street use.
• Quick Installation: Easy to insert or remove with an Allen bolt or retaining clip.
• Protection of Internal Components: Prevents excessive pressure and wear on the muffler.

When to Use a DB Killer?

• For track days or street use with noise limits.
• To quiet down an overly loud sport exhaust.
• When you want to reduce annoyance or resonance at low RPMs.

Maintenance and Tips

• Regularly check for stuck dirt or carbon buildup in the silencer opening.
• Use heat-resistant bolt paste during installation to prevent seizing.
• Allow the exhaust to cool down completely before disassembly or cleaning.
