Silmen/Silman Short Punjab Silencer (Small Mouth, Chrome) – LSM3-A – For Royal Enfield Classic 350 Reborn & New Bullet 350 (2023+ J-Series)

Bring back the classic Punjabi “dug-dug” thump on your J-Series Royal Enfield with the Silmen (Silman) Short Punjab Small Mouth Chrome Silencer – LSM3-A. Built for riders who want the old-school Bullet vibe on modern platforms, this exhaust is designed as a direct bolt-on upgrade for the Classic 350 Reborn and New Bullet 350 (2023+)—including color variants like Battalion Black. 

The small mouth outlet creates a tighter, punchier sound compared to “big mouth” cans—more rhythmic, more “traditional,” and less hollow. The mirror-finish chrome enhances the retro look while staying durable for daily use. Ideal if your stock silencer feels too quiet, or you want a shorter “Punjab” stance without welding/cutting.

OEM vs Aftermarket note: This is an aftermarket performance-style silencer (not a Royal Enfield OEM muffler). If you want stock restoration for older UCE bikes, that requires a different OEM silencer assembly and mounting.

FAQs 

1. Will this fit my Bullet 350 Battalion Black?
   Yes—Battalion Black is a variant of the New Bullet 350 (2023+ J-Series). This silencer is listed for Bullet 350 (2023+) fitment. 

2. Does it fit Classic 350 old model / UCE / Electra / Thunderbird?
   No. UCE bikes use a different exhaust/mounting system and OEM muffler part families. This is for J-Series only. 

3. Small Mouth vs Big Mouth—what should I buy?
   Small Mouth = tighter outlet, punchier/cleaner “dug-dug” beat.
   Big Mouth = wider outlet, generally louder + deeper + more hollow tone (depends on internal design). 

4. Is tuning/remap required after installation?
   Typically no for a slip-on style muffler on stock J-Series setups, but results can vary by condition/other mods. If you have intake + decat + other changes, consult a mechanic for best ride quality.

5. Is this road-legal?
   Sound/emission rules vary by state and enforcement. This is a sound-style aftermarket silencer; use responsibly and follow local regulations.
