The AVP Stainless Up-Pipe Kit is a premium replacement for the failure-prone factory exhaust feed system on 2003–2007 Ford 6.0L Power Stroke engines (OE part numbers: 5C3Z-6K854-BA, 5C3Z6K854BA, 3C3Z-6K854-DA, 3C3Z6K854DA, 1843901C91, 1846581C1). Factory up-pipes that route exhaust from the manifolds to the turbocharger are a common source of cracks, leaks, and loss of turbo drive pressure—leading to higher EGTs and reduced performance.
These heavy duty pipes are built from high-grade stainless steel and feature internally shielded flex couplings to resist burn-out and maximize service life. Engine vibration is isolated by the flex design for better reliability and long-term sealing even under high loads and tuned settings. Optimized pipe diameters ensure efficient transfer of exhaust heat to the turbo, improving both turbocharger response and durability.
This direct-fit kit installs with no modifications required, and you keep your old up-pipes—no core charge or extra steps. Perfect as a preventative upgrade or during engine, transmission, or turbo repairs.
OE cross reference numbers ensure exact fit and easy dealer/service lookup.
