6.4 DPF DOC CAT DELETE???????

Hey guys, Im new to the 6.4 and need some help. What are the differences between a DPF delete, DPF/DOC delete, and a DPF/CAT delete? Which ones should i use to make the most power or should I delete all three?
Thanks in advance guys!

A DPF delete is just deleting the DPF only and leaving the DOC. A DPF/DOC is the same thing as a DPF/CAT delete. It fully removes the unit together. You have to unbolt the DPF and DOC when you just do a DPF delete because they are all one unit. I recommend doing a fully DPF/DOC delete. It's easier and you never have to worry about the DOC clogging up. A free flowing exhaust is much better anyway on a diesel.

They are all different ways of saying the same thing. DPF is dpf. Cat is also know as DOC. Delete them all.

Yes, ford refers to the CAT as a DieselOxidationCatylist.

DOC=CAT
DPF/CAT delete = DPF/DOC delete

Thumbs up

Just be sure to save some extra $$$ for the fine you'll get for deleting them . When I say extra I mean like 40k!

Huh???? 10k or 40k fine???? I havent heard anything about this. Is it a per state thing? Im really thinking about buying a 6.4L in the spring. Im in ohio, I'm the owner of a Landscaping company, all my trucks are register'd commercial and dont need e-check or anything. If i buy a 6.4L i was gonna put a straight pipe on it right away. So whats the deal???
