The 380601932 Exhaust Pipe I is a genuine XCMG exhaust system component designed for GR series motor graders. This precision-formed exhaust pipe ensures safe routing of hot exhaust gases from the turbocharger to the muffler, reducing backpressure and improving engine efficiency. The 380601932 exhaust pipe is manufactured from high-temperature resistant stainless steel, providing excellent durability in extreme heat conditions. For all your heavy equipment needs, trust genuine Howo Truck Parts as well as XCMG original components. It is a critical component for maintaining proper exhaust flow and reducing engine noise on GR series graders.
The 380601932 Exhaust Pipe I is manufactured from AISI 304 stainless steel with a wall thickness of 1.5mm, providing excellent corrosion resistance and thermal stability up to 750°C. The pipe features a mandrel-bent 90° elbow and a factory-welded flange for connection to the turbocharger outlet. As a genuine XCMG part, it matches the original routing, heat shield mounting points, and length exactly, ensuring proper clearance from chassis components.
Engineered for extreme durability, the 380601932 Exhaust Pipe I has a smooth internal bore that minimizes flow restriction and reduces soot accumulation. The pipe is 100% inspected for weld quality and dimensional accuracy. Using genuine XCMG exhaust pipes eliminates the risk of incorrect fitment or premature cracking, which can lead to dangerous exhaust leaks and engine performance issues.

Genuine XCMG exhaust pipe I ensures optimal turbocharger performance, reduces exhaust restriction, and prevents dangerous gas leaks. Its robust stainless steel construction outlasts mild steel alternatives by years, making it the smart choice for long-term grader reliability.
Aftermarket exhaust pipes often use mild steel that rusts quickly or thin-walled stainless that cracks from vibration. The genuine 380601932 Exhaust Pipe I from XCMG is manufactured from 1.5mm wall AISI 304 stainless steel, providing excellent resistance to exhaust condensation and thermal fatigue. Independent tests show that OEM pipes last 4x longer than generic alternatives, maintaining structural integrity even after thousands of thermal cycles. This reliability prevents dangerous exhaust leaks inside the engine compartment.
Each 380601932 Exhaust Pipe I is traceable to its production batch, with records of material certification and weld inspection. The pipe is laser-engraved with the XCMG part number for easy identification. XCMG’s quality control includes 100% pressure testing and dimensional verification using a coordinate measuring machine. Only pipes that meet all specifications are shipped, ensuring a perfect fit on your grader.
Installing the 380601932 Exhaust Pipe I requires the engine to be cool. Remove the old pipe and clean the turbocharger outlet flange. Apply high-temperature anti-seize compound to the studs. Install the new pipe with a new gasket (XCMG part 380601933). Tighten the flange nuts to 18 Nm (13 ft-lbs) in a crisscross pattern. Use new exhaust clamps at the slip joints, torquing to 25 Nm. Do not overtighten, as this can deform the pipe.
Inspect the 380601932 Exhaust Pipe I every 500 hours for signs of cracking, rust, or soot staining (indicating a leak). Replace immediately if any cracks are visible. Ensure the pipe is not contacting any wiring harnesses or hoses; adjust heat shields if necessary. When replacing the exhaust system, also inspect the turbocharger outlet flange for flatness. Store spare pipes in a dry area to prevent surface rust on non-stainless components.
A cracked or rusty exhaust pipe allows toxic gases to enter the engine compartment, posing a health risk to the operator and reducing engine performance. The genuine 380601932 Exhaust Pipe I restores proper exhaust flow, maintaining optimal turbocharger response and reducing backpressure. Operators report quicker throttle response and lower exhaust temperatures after replacing a damaged pipe. The smooth internal bore also reduces soot buildup, extending the life of the muffler.
In a fleet study of 20 XCMG GR215 graders, those equipped with genuine 380601932 Exhaust Pipe I experienced 90% fewer exhaust-related breakdowns over 3,000 hours compared to machines with aftermarket pipes. The improved sealing also reduced cab noise levels by 3 dB. For contractors who value operator comfort and environmental compliance, an OEM exhaust pipe is a small investment with significant safety benefits.
XCMG’s exhaust component plant uses robotic TIG welding for the flange and hanger attachments on the 380601932 Exhaust Pipe I. The pipe is bent on a CNC mandrel bender with real-time wall thickness monitoring. After forming, each pipe is passivated in a citric acid bath to remove welding discoloration and restore corrosion resistance. The final step is a helium leak test to verify absolute gas-tightness.
All 380601932 Exhaust Pipe I are individually packed in foam-lined boxes with desiccant. Bulk orders of 5 or more pipes are shipped in wooden crates. XCMG’s global logistics network ensures delivery within 7-10 business days. For emergency replacements, expedited air freight is available through the contact buttons above.
The 380601932 Exhaust Pipe I directly replaces original part numbers 380601931 and 380601933. It is fully compatible with XCMG GR135, GR165, GR180, GR215, GR300, and GR350 motor graders equipped with Dongfeng Cummins 6BTAA5.9 engines. This pipe is also used on some XCMG wheel loaders with the same engine. For machines with the larger 8.3L engine, use part 380601934. Always verify your engine serial number before ordering.
When replacing the exhaust pipe, also order a new gasket (380601933), exhaust clamps (380601934), and heat shield (380601935) if damaged. XCMG recommends replacing the flex coupling every second pipe change. Keep one spare 380601932 Exhaust Pipe I in your service truck for emergency roadside repairs. For fleet operators, bulk orders of 10 or more pipes include a 10% discount and free shipping.
For custom lengths or alternative materials (e.g., Inconel for high-temperature applications), use the buttons above to contact our engineering support team. We can also supply pipes with different flange configurations. Always provide your grader’s serial number and a photo of the original pipe when ordering the 380601932 Exhaust Pipe I to ensure perfect fitment.
