HKK 63mm dB Killer for Royal Enfield Punjab Silencers
Looking for a 63mm dB Killer for your Royal Enfield Punjab exhaust? The HKK 63mm dB Killer is designed for compatible Short Punjab and Long Punjab Big Mouth silencers, providing a practical solution for riders who want better control over their aftermarket exhaust sound.
A dB killer, also known as an exhaust baffle or sound reducer, is an insert fitted inside a motorcycle silencer to regulate exhaust gas flow and help reduce exhaust noise.
Whether you use a Short Punjab or Long Punjab Big Mouth exhaust, this HKK exhaust insert is intended for compatible applications where the existing baffle needs replacement or an exhaust sound-control insert is required.

Why Use a 63mm dB Killer in Your Punjab Silencer?
Punjab-style exhausts are popular among Royal Enfield enthusiasts for their traditional design and distinctive exhaust character. However, not every rider wants to operate an aftermarket silencer without a sound-control insert.
A 63mm dB killer helps regulate exhaust gas flow through a compatible silencer and can reduce the noise produced by the exhaust system.
The actual sound reduction depends on the internal design of the silencer, motorcycle configuration and installation.
Short Punjab vs Long Punjab – Compatibility Guide
Short Punjab and Long Punjab silencers have different body lengths and designs, but both can have Big Mouth exhaust configurations.
The HKK 63mm dB Killer is intended for compatible versions of both styles. Before ordering, compare the actual internal fitting dimensions and mounting arrangement of your existing exhaust.
Do not choose an exhaust insert based on the external appearance of the silencer alone.
