BD UpPipes for the 1999.5-2003 Ford 7.3L PowerStroke replace the factory exhaust feed system (exhaust manifold to the turbocharger) which is prone to leakage due to the deterioration of the exhaust crush donuts. The escaping exhaust and heat from the deterioration eventually burns out the feed pipes, causing a loss of turbo drive pressure and increased EGT’s.
New designed piping with sizing to maximize transfer of heat energy to the turbo come with less restrictive, internally shielded expansion bellows that are not exposed to exhaust gases, thus reducing the chance for burn out like the factory system. The turbo Y-adapter is made from the same proven high-silicon ductile iron used to build the infamous BD exhaust manifolds.
The BD UpPipes are a durable, longer-life replacement for this common PowerStroke problem and is perfect as an upgrade while performing other engine or transmission repairs.
