HK Long Punjab Silencer Big Mouth (Chrome) for Royal Enfield Classic 350 Reborn (J-Series) & New Bullet 350 2023+ (Battalion Black)

HK Long Punjab Big Mouth Chrome silencer for Classic 350 Reborn & New Bullet 350 (2023+). Deep loud thump. J-Series only. Bolt-on fit.

If you want the full “Punjab” silhouette with a louder, deeper presence, the HK Long Punjab Big Mouth Chrome Silencer is the right choice. The long body keeps the classic Royal Enfield rear profile, while the big-mouth outlet gives a more open exhaust character—typically deeper bass and higher volume than small-mouth Punjab styles.

This silencer is intended for J-Series 350 bikes only: Classic 350 Reborn (BS6) and All New Bullet 350 (2023+), including popular variants like Battalion Black. It is not meant for UCE models (older Classic/Bullet/Electra), 650 Twins, or Himalayan platform bikes.

Because the aftermarket exhaust market has multiple similar copies, we keep returns low by recommending a quick match before dispatch: clamp type, inlet diameter, and mounting point distance. If you share a photo of your stock silencer mount, we can confirm in minutes.

FAQs 

1. Will this fit Bullet 350 Battalion Black?
   Yes—Battalion Black is a New Bullet 350 (2023+) J-Series variant. This listing is for New Bullet 350 J-Series.

2. Does it fit old Classic 350 / Electra / Bullet UCE?
   No. UCE exhaust mounting differs. This is for J-Series only.

3. Long vs Short Punjab silencer—what should I choose?
   Long = full classic stance, more “traditional” look.
   Short = compact look, sportier rear profile.
   Sound varies, but long cans often feel smoother/continuous while short cans feel sharper.

4. Big Mouth vs Small Mouth—what’s the sound difference?
   Big Mouth usually gives deeper + louder + more open output.
   Small Mouth is typically punchier/beat-focused and slightly less open.

5. Is it legal / challan risk?
   Aftermarket sound-style silencers can be louder than OEM; local enforcement varies. Use responsibly and at your discretion.
