Ok, so I see everyone makes headers for the E350 7.5L if you have the C6......what about us guys with the E4OD? I have a cutaway motorhome.

 

These are nice. Banks is another option. If it lists a C6 then you probably do not want those. If you have an E4OD then you have an EFI engine and they have different ports so you have to use the right headers. BTW glad you are taking the step to headers. That motorhome will thank you!

I hear it's "night and day" on a 460 motorhome once headers are added, lots of power free'd up.
