This is the OEM Silencer Assembly (Muffler) for the Royal Enfield Classic 350 UCE (pre-BS6), supplied under factory part number 472046. It is the exact exhaust fitted on the motorcycle at production—ensuring correct back-pressure, throttle response and long-term durability. The part is listed in Royal Enfield’s official microfiche as “Silencer assy – Classic 350 – New” and replaces earlier supersessions like 572046/E. 

Use this unit when restoring stock sound on carb/EFI UCE Classics or when replacing a damaged or rusted muffler. It’s engineered to work with the OE header pipe and mounting points—no cutting or fabrication required. Choosing the genuine silencer avoids tuning issues common with aftermarket cans and keeps emissions compliance for BS3/BS4 UCE models. Not for the All-New (J-series) Classic 350 (Reborn). Verified fitment is for Classic 350 UCE (pre-BS6); see compatibility table below. Dealer confirmations: Bike-Parts-RoyalEnfield (official fiche portal) and Part On Wheels list 472046 specifically for Classic 350 “New/UEC” models (incl. 2020).

FAQs:

Q1. Will this fit the All-New Classic 350 (Reborn, J-series)?
No. This is for UCE Classic 350 (pre-BS6). The Reborn/J-series uses different exhaust parts. 

Q2. Does it include the heat shield and clamps?
This listing is for the silencer assembly only. Heat shields, clamps, gasket and hardware are separate items (the “silencer comp with guard” has its own P/N).

Q3. Can I use it on BS3 models?
It’s designed for UCE Classic 350. Many BS3 bikes use a similar layout, but model-year verification is required; check your VIN and current part number before purchase (BS3 row marked ❓).

Q4. Why choose OE over aftermarket?
OE ensures correct fueling/back-pressure, long life and legal noise/emissions compliance for BS3/BS4 UCE Classics.
