Upgrade your Royal Enfield J-Series exhaust setup with the EAZ Silman LPA-22 Dual-Sensor C-Bend Pipe. Designed with dual O2 sensor ports, C-Bend free-flow construction and a heat-resistant matte black finish, this aftermarket header pipe is designed for compatible Classic 350 Reborn and New Bullet 350 Battalion Black configurations.
Long Description
The EAZ Silman LPA-22 Dual-Sensor C-Bend Pipe Free Flow is an aftermarket exhaust header/bend pipe designed for Royal Enfield’s modern J-Series 350cc platform.
The key feature of the LPA-22 is its dual-sensor configuration, providing two dedicated O2-sensor ports for compatible motorcycles that use a dual-sensor exhaust arrangement. EAZ’s product listing specifically identifies it as compatible with BS6 Phase 2 / OBD-2 requirements.
Its C-Bend design provides a free-flow exhaust path and is intended for riders looking to modify the stock exhaust setup and pair the header with a compatible aftermarket silencer.
The pipe features a high-temperature-resistant matte black finish, making it particularly suitable for the blacked-out styling of Battalion Black and other dark-finish J-Series motorcycles.
The LPA-22 is primarily listed for Classic 350 Reborn and New Bullet 350 Battalion Black, while EAZ’s product page also states that the pipe fits the broader J-platform including Meteor 350 and Hunter 350. Because sensor configuration varies between J-Series generations/variants, customers should verify their motorcycle’s sensor arrangement before ordering.

Installation
Professional installation is strongly recommended.
Before installation:
- Confirm that the motorcycle uses the required dual O2-sensor configuration.
- Check the exhaust-port connection and bend-pipe alignment.
- Transfer/install the compatible O2 sensors carefully.
- Check mounting-point alignment.
- Ensure adequate clearance from the engine, frame, foot controls and rider’s leg.
- Connect the compatible silencer.
- Check all exhaust joints for leakage.
- Verify that there are no sensor/ECU warning lights after installation.
Do not install a dual-sensor pipe on a single-sensor motorcycle without confirming the correct exhaust and sensor configuration.
Important Note
This is an aftermarket SILMAN free-flow exhaust component and is not a Royal Enfield Genuine OEM exhaust header.
Changing the exhaust header/catalytic-converter arrangement can affect exhaust sound, emissions and ECU operation. Actual results depend on the motorcycle, sensor configuration, silencer and other exhaust modifications.
For road use, ensure the completed exhaust system complies with applicable noise and emissions regulations.
