HKK Indore HKP2A L Bend Pipe 38mm for Royal Enfield 350 UCE BS3 – Without Sensor

Replace a rusted, dented or leaking exhaust header on your compatible Royal Enfield 350 UCE BS3 motorcycle with the HKK Indore HKP2A Short Bend “L” Pipe.

This chrome-finish 38 mm bend pipe is made for older carburettor-type UCE exhaust systems that do not use an oxygen sensor.

Please note: This is an HKK Indore aftermarket bend pipe. It is not a Royal Enfield genuine or OEM exhaust component.

Chrome Finish and Construction

Installation Guidance

• Professional installation is recommended.
• Allow the engine and existing exhaust to cool completely before removal.
• Compare the new pipe with the old pipe before installation.
• Confirm that no oxygen sensor is required on your motorcycle.
• Use a new engine-head exhaust gasket where required.
• Align the pipe naturally without forcing, bending or hammering it.
• Confirm adequate clearance from the engine, frame, brake pedal, centre stand and footrests.
• Check both exhaust joints for leakage after installation.
• Recheck fasteners after the first complete heat cycle.

Sound and Performance Expectations

Replacing the bend pipe may change the exhaust note when it is used with an aftermarket silencer. The final sound depends mainly on the rear silencer, exhaust sealing, engine condition and complete exhaust setup.

No guaranteed increase in horsepower, torque, pickup or mileage is promised.

Care and Maintenance

• Allow the pipe to cool fully before cleaning.
• Use mild automotive shampoo and a soft microfibre cloth.
• Avoid acidic cleaners, steel wool and abrasive pads.
• Dry the chrome surface after washing.
• Inspect both exhaust joints for leakage.
• Check the heat-shield mounting points and exhaust fasteners periodically.
• Use only a chrome-safe polish when required.

Important Fitment and Return Note

This is a configuration-specific exhaust component. Confirm the motorcycle model, year, UCE BS3 generation, no-sensor exhaust arrangement, pipe diameter and both connection points before installation.

Do not start the motorcycle until fitment has been checked. Once installed or heated, the pipe may develop tool marks, joint marks, carbon deposits or heat-related discolouration.

Compliance Note

Changing an original exhaust component may affect noise, emissions and road-use compliance. Requirements vary by motorcycle and location. No BS4, BS6, emission, PUC or road-use approval should be assumed for this BS3 no-sensor pipe.
