Genuine Sinotruk HOWO Cylinder Head Exhaust Pipe Assembly - VG1238040012

The exhaust system of a heavy-duty truck is under constant thermal siege. The VG1238040012 Cylinder Head Exhaust Pipe Assembly is the frontline component responsible for channeling high-temperature gases away from the WD615 engine's cylinder head.

Unlike low-cost cast-iron imitations that tend to warp or crack under the intense "heat-cool" cycles of long-haul trucking, this genuine assembly is manufactured using high-grade, heat-resistant alloy. It is precision-engineered to maintain its shape and sealing integrity even at peak operating temperatures. A failing exhaust pipe doesn't just make noise; it disrupts engine backpressure and can lead to turbocharger inefficiency or even cabin fumes. Replacing your worn manifold pipes with the authentic VG1238040012 ensures that your Sinotruk engine breathes correctly, keeping fuel consumption stable and engine performance at its peak.
