The MBRP FAL2313 Heavy-Duty Up-Pipe Assembly for your 2003-2007 6.0L Powerstroke is designed to add durability and reliability while addressing the common failure points of the factory y-pipe. Built from aluminized steel this Y-Pipe assembly features heavy-duty bellows that resist cracking and leaking over time. This Y-Pipe Assembly is a direct replaceme for the factory component. It will retain the use of the EGR because it connects to the factory up-pipe flange that is after the EGR riser.
