Silman Short Punjab Silencer Chrome for Royal Enfield UCE – 45mm / 57mm

Silman Short Punjab Silencer for Royal Enfield UCE – Chrome | 45 mm Small Mouth & 57 mm Big Mouth

Bring back the classic Royal Enfield Punjab-style exhaust look and thump with the Silman Short Punjab chrome silencer, made for compatible Royal Enfield UCE Classic, Bullet Standard and Electra motorcycles.

This listing combines the two most useful outlet choices in one place:

• 45 mm – Small Mouth: for riders who prefer the traditional Short Punjab appearance with a comparatively tighter outlet.
• 57 mm / 2.25 inch – Big Mouth: the wider-mouth version shown in the product photos, chosen by riders looking for the bolder Punjab-style rear profile and deeper free-flow exhaust character.

Important: This is an aftermarket Silman exhaust silencer. It is not a Royal Enfield Genuine OEM silencer.

Compatible Royal Enfield Models

Not for: Classic 350 Reborn / J-Series, Meteor 350, Hunter 350, New Bullet 350 (J-Series), Goan Classic 350, Himalayan, Interceptor 650, Continental GT 650, or other platforms unless separately verified.

Choose the Correct Mouth Size

The mouth size refers to the outlet style of the silencer, not the engine capacity. Select the variant according to the exhaust style you want.

Why Riders Choose the Silman Short Punjab

• Well-known Silman / Silman Pooja aftermarket exhaust design
• Classic Short Punjab / Punjabi / Dholki silencer styling
• Mirror chrome finish that suits older Royal Enfield UCE motorcycles
• Free-flow internal design
• Compact body compared with long Punjab silencers
• Available in both small-mouth and big-mouth outlet styles
• Popular for Classic, Standard / Bullet and Electra customization
• Useful as an aftermarket replacement or appearance-and-sound modification

57 mm Big Mouth Version

The 57 mm Big Mouth is the wider-outlet version. 57 mm is approximately 2.25 inches, a size commonly associated with Silman's wider Punjab-style outlet. This version is especially suited to buyers searching for terms such as Royal Enfield 57mm silencer, Short Punjab Big Mouth, Punjab silencer, Bullet heavy sound silencer, Classic 350 free-flow silencer or 2.25-inch Royal Enfield silencer.

45 mm Small Mouth Version

The 45 mm Small Mouth keeps the Short Punjab body style but uses the narrower outlet configuration. It is the better choice for buyers specifically looking for the traditional small-mouth Punjab appearance rather than the large 57 mm exit.

Sound Character

Both versions are aftermarket free-flow silencers and are intended to produce a more pronounced exhaust note than a standard stock-style silencer. The 57 mm Big Mouth is generally chosen for a fuller, deeper and more open exhaust character, while the 45 mm Small Mouth has a comparatively tighter outlet character.

Actual exhaust sound is not fixed. It varies with engine condition, 350 cc vs 500 cc engine, bend pipe, catalytic converter configuration, exhaust leaks, carburettor / EFI setup, tuning and other modifications. A specific decibel level or exact sound cannot be guaranteed.

Fitment Notes – Read Before Ordering

• This listing is for UCE-generation motorcycles only.
• Do not order for Classic 350 Reborn, Meteor 350, Hunter 350 or New Bullet 350 J-Series based only on the bike name.
• Check your existing bend-pipe diameter, mounting position and model generation before installation.
• A reducer / adaptor bush may be required on some UCE exhaust configurations depending on model year and bend pipe.
• Clamp, bush, rubber cap or other small fitting hardware can differ by production batch; do not assume additional hardware unless specifically shown or confirmed with the selected stock.
• Professional installation is recommended to prevent exhaust leakage, incorrect alignment or mounting stress.

Installation Guidance

1. Allow the existing exhaust to cool completely.
2. Remove the original silencer mounting bolt and exhaust clamp.
3. Check the bend-pipe joint and use the correct bush / sleeve where required.
4. Slide the Silman silencer into position without forcing the joint.
5. Align the rear mounting bracket before tightening the clamp and mounting fastener.
6. Start the motorcycle and check for exhaust leakage or abnormal vibration.
7. Re-check mounting hardware after the first few heat cycles.

Which Variant Should I Buy?

Choose 45 mm Small Mouth if you specifically want the narrower traditional Punjab outlet.

Choose 57 mm Big Mouth if you want the wider 2.25-inch outlet shown in the product photos and the more aggressive Big Mouth appearance.
