HK Long Punjab Silencer Small Mouth (Chrome) for Classic 350 Reborn & Bullet 350 J-Series (HK-LP-LONG-SM)

Bring back the old-school “Punjab thump” on your J-Series Royal Enfield 350 with the HK Long Punjab Chrome Silencer—built for riders who want a deeper, bassy exhaust note and a strong visual upgrade. This long-body, chrome-finish exhaust is commonly chosen by Classic Reborn owners and new Bullet (Standard Reborn/Battalion Black) riders who want a loud, traditional Dug-Dug character without the bulky stock look.

This is an aftermarket performance-style silencer (not an OEM Royal Enfield part), typically sold as a free-flow/empty-style “Punjab” exhaust, so the sound is noticeably louder than stock. Some sellers describe internal packing/insulation variations depending on batch, so real-world sound can vary slightly.

Ideal use-cases: city presence, classic styling, and riders who prefer a bold exhaust note. If your priority is legality/noise control, keep the stock silencer. For the correct fitment and to reduce returns, confirm your bike is J-Series (Classic Reborn / New Bullet 350), not UCE.

FAQs 

1. Will this fit Classic 350 UCE (2010–2020) / Electra / old Bullet?
   No. This listing is for J-Series bikes (Classic Reborn / New Bullet 350). UCE exhaust fitment differs. 

2. Is this OEM Royal Enfield?
   No—this is an aftermarket HK “Long Punjab” style silencer, chosen for sound and styling. 

3. How loud is it compared to stock?
   Expect a much louder, deeper note than stock. Many sellers describe it as free-flow/empty-style; sound can vary slightly by batch/packing description. 

4. Do I need welding or modification?
   Usually it’s sold as a bolt-on style exhaust, but exact fit depends on your joint/bend-pipe setup. To avoid returns, confirm your bike model (J-Series) and compare mounting points before installing. 

5. Will it affect warranty / legality?
   Any aftermarket exhaust can impact warranty decisions and may violate local noise/emission rules. Use responsibly; keep the stock exhaust if you need strict compliance.
