This exhaust pipe routes combustion gases from the engine manifold to the downstream aftertreatment components. It is a formed steel tube that connects the turbocharger outlet to the diesel oxidation catalyst or particulate filter inlet. A cracked or corroded pipe allows exhaust leakage, which reduces backpressure and can trigger diagnostic trouble codes for the emissions system. As an original AGCO component, the pipe is formed to match the exact bend radius and flange orientation of the production assembly, so no additional bracketing or alignment is needed during installation. Replace the gasket at each joint when reinstalling, and verify the pipe does not contact the chassis under thermal expansion.
