• Description:

  This is the genuine Ford turbocharger exhaust outlet pipe, listed in Ford catalogs simply as Exhaust Pipe. It is the heavy walled formed pipe that bolts to the turbine outlet of the turbocharger and carries hot exhaust gas away from the turbo and down into the diesel oxidation catalyst and the rest of the aftertreatment system, sealing at both ends with a gasket and clamp or flange hardware so no exhaust escapes upstream of the sensors. Verified fitment is the 6.7L Power Stroke diesel in Ford Super Duty trucks across the 2020 through 2024 catalog range, covering F-250, F-350, F-450 and F-550 applications. Symptoms of a failed pipe include a loud exhaust ticking or roaring sound from under the hood that changes with engine load, a strong diesel exhaust smell entering the cabin, black soot tracks around the joint faces, a visible crack in the pipe wall or a leaking flange, reduced boost and sluggish acceleration because escaping gas robs the turbine and the aftertreatment sensors, and stored codes for exhaust pressure or regeneration faults because the system cannot reach the temperature it needs. Cracks usually start at the weld seams and at the flange radius where thermal cycling concentrates stress. When replacing this pipe, always renew the gaskets and clamp hardware and inspect the mating flanges for warp, and treat the exhaust flange fasteners as single use where Ford specifies torque to yield hardware, since reused stretched fasteners will not hold clamping force at exhaust temperature and the joint will leak again. Genuine Ford construction provides the correct wall thickness, bend routing and flange geometry so the pipe clears the surrounding components and holds a gas tight seal through full diesel exhaust temperature cycles.
