Royal Enfield 144055 – Exhaust Pipe Std Plated (Bend Pipe) for Old Bullet 350 / Deluxe / Machismo / Campus / Electra 4S–5S (Cast-Iron 350 Only)

Royal Enfield part 144055 is the genuine “EXHAUST PIPE STD – PLATED” front bend pipe for old-model 350cc cast-iron Bullets. Official retired-models parts catalogues list 144055 as Exhaust pipe Std – Plated, and multiple trusted dealers describe it as the standard front exhaust/bend pipe for Bullet 350 (1955), Deluxe, Machismo, Campus and Electra 4S–5S (KS/ES).

This pipe connects the cylinder head to the main silencer and sets the alignment and back-pressure for your exhaust. Over time, original pipes rust, dent, or get bent after a fall or repeated silencer changes. Cheap local “universal” bend pipes often have wrong bends or poor plating, leading to fouling with the frame, poor sealing at the head, and premature rust.

With 144055, you’re getting the factory-spec geometry and plating – correct flange position at the head, proper curve to clear the frame/footrests, and right outlet angle for original-style silencers and popular short silencers (many international sellers list 144055 as “long pipe for short silencer 350cc”).

Perfect for restoration builds, export bikes, or returning a modified Bullet back to stock, this is the safest choice when you want OEM fit and finish, reduced trial-and-error at the denter, and fewer exhaust leaks.

⚠️ Note: This is for old 350cc cast-iron Bullet family only – not for UCE / J-Series / 500cc / Himalayan / 650 Twins.

FAQs

Q1. Will 144055 fit my Bullet 350 UCE or Classic 350 Reborn?
No. 144055 is confirmed only for old cast-iron 350 Bullets (Std/Deluxe/Machismo/Campus/Electra 4S–5S). UCE and J-Series bikes use different cylinder heads and exhaust routing, so this pipe will not fit.

Q2. Is this the front bend pipe only or a full silencer?
144055 is the front exhaust pipe / bend pipe only. It runs from the engine head to the silencer. You will still need a separate silencer (standard or short) plus clamps and exhaust gaskets.

Q3. Can I use this pipe with a short / Goldstar-style silencer?
Many international listings describe 144055 as an “exhaust pipe long for short silencer 350cc”, which means it is commonly used as the front pipe when fitting short silencers to old 350 Bullets. As long as the silencer has the correct inlet size and mounting bracket, it will work.

Q4. How do I confirm this will match my current exhaust?
Check that your bike is an old 350 CI Bullet (not UCE/J), and compare:

• Flange shape at the cylinder head

• Pipe exit angle at the rear

• Mounting points and frame clearances
  If your existing pipe looks like the OE Bullet 350 bend and your model matches the table above, 144055 is the correct replacement.

Q5. Does the pipe come with nuts, studs or gaskets?
No. This part number covers the pipe only. Reuse your existing hardware if in good condition, or order fresh exhaust nuts, studs and copper/asbestos-type gasket separately.
