Replacement REPF963501 Turbocharger Y-Pipe Up-Pipe Assembly for Ford 6.0L Powerstroke Diesel

The Replacement REPF963501 Turbocharger Y-Pipe is a direct OEM-equivalent exhaust up-pipe assembly engineered for the 2003–2007 Ford F-250 Super Duty and F-350 Super Duty equipped with the 6.0L Powerstroke turbocharged diesel engine. This Y-pipe, also commonly referred to as the turbo up-pipe, routes exhaust gases from the dual exhaust manifolds up to the turbocharger inlet, playing a critical role in maintaining pre-turbo exhaust pressure and overall engine performance.

The factory up-pipe assembly is a well-known wear item on the 6.0L Powerstroke platform. The corrugated bellows sections are particularly prone to heat fatigue and cracking over time, resulting in pre-turbo exhaust leaks that rob power and reduce turbocharger efficiency. This replacement unit restores proper exhaust flow and sealing to factory specifications.

Key Features:

• Direct OEM replacement design — bolt-on installation with no modifications required
• Engineered to withstand the high-pressure, high-temperature environment of a turbocharged diesel exhaust system
• Replaces Ford OEM part numbers: 5C3Z-6K854-CA, 5C3Z6K854CA
• Also cross-references aftermarket part numbers: 679-011, 1846581C1
• Restores proper pre-turbo exhaust sealing and boost efficiency
• Designed specifically for the Ford 6.0L (363ci) OHV V8 Power Stroke Turbo Diesel (VIN code P)

This turbocharger Y-pipe is the correct solution for restoring lost power and correcting exhaust leaks caused by a fatigued or cracked factory up-pipe on the 6.0L Powerstroke platform.
