Well you are the perfect person to talk to then, hahaha. I know I've already stuck my foot in my mouth by doing what I did, but the fact is that the sensors read back pressure right? If that is the case then I shouldn't have to worry about any thing going wrong with the truck. Yes I know as far as emissions go I would be screwed but I got that covered is there anything else that I'm missing?

When the exhaust is smoking are the tires also smoking?

Any noticeable difference in power?

[sttstroke]

does it run better?

The sensors are the pressure inlet/outlet tubes. You guys pretty much understand how the dpf's work. The trick is to make the truck think that the backpressure is within the normal operating zone. I cant tell anymore because it is proprietary information, but you guys are on the right path

well as long as their just gutted and theirs no obvious pipe there i wouldnt think of any reasor a dealer would take em off and look after all ford doesnt wasnt to pay one of their technitians 2 hours labor to take the exhaust off the truck to see if theirs a reason they can deny a waranty claim on a procedure that takes an hour of shop labor to perform jmo

I would think that the dealer would easily be able to tell that the exhaust has been modified. They work on them all day long, every day. When his comes in sounding "like a 747", I think they will know. Only time will tell, I guess.

Along with the obvious sound difference I think it will be smoking like a 6.0 and they will know why.

Exhaust alone should not damage anything because the computer is still in control of the fuel and the boost based on IAT, ECT, Boost, and maybe some other things that would cause it to decrease fuel or boost. If you modify the programming the gutted exhaust should actually save the motor to some point because it should lower the EGT. The question is can they tell if the programming were modified as they have claimed.

In a warranty dispute they would have to prove that the unrestrictive exhaust caused some damage. It seems unlikely they would have any problem at all with a modified exhaust other than emissions problems. If your vehicle fails an emissions test and you loose the registration you would need to replace the parts where a delete pipe could have been easily reversed.

The exhaust modification warning is in reference to damaging the DPF. If it's not there then there is nothing to damage.

The real killer is the reprogramming warning. They would likely refuse any warranty claim on an engine failure if they could tell reprogramming had been done or if they had a way to tell a fooler was used.

I spoke with the owner of my small town ford dealship owner over lunch a few weeks ago, He said that if a 08 6.4 came in and it had any exhaust mods done, weather it was a filter back, or a turbo back the warrenty Will be voided no ands ifs or buts about it. He went on to say that it is a goverment law to have the filters on there and the moss act does not apply to the new 07 regulatshions.
