6.4L mods??
I stopped at a dealership to take a look at the new '08 PSD's, have no interest in one since my '99 has provided for me well, but visiting with the salesman about them and he said it is illegal to modify the exhaust in any way. Just wondering if that was true and what will that do to the diesel aftermarket companies?
His reason was because the engine runs hotter and would burn up without all cooling chambers on the exhaust. My thinking is it could run cooler since you don't have all the emissions "crap" on it like the particulate filters, cat, and whatever else is included; let the thing breath and remove all the restrictions.
Any other thoughts?

It is true that the exhaust is all a part of the emmissions system on the 6.4L. However there will be mods available for it. The engineering on these mods is already done, they are just waiting for CARB approval. Hopefully they will be able to get some approvals so that those who want to mod can do it.

Its been illegal to defeat or modify emissions equipment since they have been in existence, for anyone that is in the sales or repair of automotive vehicles. If you have a state inspection requirement, it may be an issue as well. The electronics on the 6.4 are so ingrained into the total system, it will create driveability issues if you remove them without doing extensive reprogramming.

Also, Banks said that the DPF really does not restrict flow as much as people may think and removing that really would not make any difference.
Just what I was reading, I don't know squat all about this stuff.

1) For the section from the manifold to the back end of the DPF the graphic reads: "Cannot be modified; Certified components"
2) For the section from the back end of the DPF to just forward of the heat diffusers the graphic reads: "Can be modified; do not increase back pressure"
3) For the section just forward of the heat diffusers to the end of the diffusers the graphic reads: "Cooling diffuser must be utilized".
I'm loosely interpreting here but it sounds like although you have to use a cooling diffuser of some kind, it doesn't necessarily have to be OEM.
If you would like, send me your E-mail address at RVrsRUS@AOL.Com and I'll send you this Ford PDF file called "2008 Measuring Session" which has some interesting information on the specs.
