Who has a link to one?
I have a buddy who wants to do this, and I am trying to find out some info for him.
Is it as simple as swapping it out with a straight section of pipe? What sensors and all need to be deleted, and what do you do with them?
Does the truck need to be retuned before it's next startup after deleting it?
Right now he is running a Hypertech pogrammer on it. Is that a bad idea w/o doing the DPF delete?

I admittedly don't know much about the 6.4, so I need a little help and a few links.

Thanks guys :thumb:

the hypertech is desgined to work with the DPF so its fine, if a little dirty.

You cannot delete any of the sensors without driving the computer bonkers and have it eventually go into permanent regen.

There is a product called dpf-r that is a sensor fooler that you can use in place of the back pressure sensor (this is the sensor that the computer uses to determine when its time to regen), but why? If you're going to go through the effort get a spartan tuner and/or an SCT as the REAL benefits of a DPF delete are running hotter tunes for increased economy.

Thanks Josh, I think he read that, and that is what got him thinking about doing it. Was that the issue with bigrpwr's truck in it? When he laid down 500hp on the delete, intake, and Eric's tunes? I think I still have that issue in the back seat of my truck :nod:
Anyway, the biggest ?? was about the sensors and such. What do you do with them after the pipe is installed? po-po?

BTW - We should have a writup on it on this site don't you guys think?

AHHH ok.
I didn't know that.

Thanks, man :thumb:

I would highly recommend buying a pipe from a vendor that makes them all the time. It will look better, and unless you know what you are looking for, you'd never know that it didn't come that way from the factory. No sense in doing a hack-job on a nice new truck. The new pipes have bungs for the sensors and such, and they are all the right thread and the right location.

I would suggest Powerstroker67's pipes. I have one of them, and I am very pleased with it. Good fit and finish.

How do i look this guy up to get a delete pipe from him? How do they compare price wise to spartans delete pipe?

I was just checking those out actually, and I sent him the links to his site :thumb:
They look real nice.

What would you guys suggest for tunes to go along with that?

The SCT he has in his package, or Spartan, or what?

Also, 1 More question. Is this easily removable so you can put the DPF and the kitty back on for inspections?

I've heard of people removing the DPF and installing a delete pipe in under a half hour. For me it took about 1.5 hours. Still not really hard by any stretch of the imagination.

As to tuners: I like the spartan better as I feel the trans tuning is better. Thats not to say that the SCT is a bad choice. If you purchase a package from Rudy's Performance you can ge a powerstroker67 delete pipe and a spartan tuner. This is the package I have.

It is held on with 2 bolts and a clamp. The really fun part is getting all the rubber hangers off the dpf/cat when you are removing it. Use lots of PB blaster on the rubber hangers, and use a Channel-Lock to push the pins out of the rubber hangers.

The first time I did mine I removed the DPF/cat with the sensors in it (carefully). Then I removed all the sensors while I had the DPF on the shop floor. It was much easier than trying to get them to break loose under a truck. The EGT sensors will be *hard* to get out. Some people buy new ones in place of trying to get the old ones out. If you want to use the old ones, get yourself a 1/2" line wrench or a 1/2" crow foot wrench to remove the sensors. The sensors are actually 13mm, but 1/2" (12.7mm) fits better (very snug). Less chance of slipping and rounding off the fittings. Once the fittings break torque, they will practically unscrew with finger pressure. If you buy a good pipe (powerstroker67's has this) it will come with a pressure sensor fitting already in the pipe. Cheaper pipes make you remove the sensor fitting from the DPF and install it in the delete pipe. The pressure sensor connection is known for causing problems. Whatever you do, don't remove it from the DPF. Before you install the new pipe in your truck, test fit the sensors. Use lots of antisieze. And for the love of god, don't tighten them down like they came from ford. Ford uses a gorilla with a 12' cheater pipe to put them in. They don't need to be that tight. Just enough so they don't fall out.

I would suggest installing the delete pipe without the sensors in it after you get all the sensors test fitted. That way you can't break anything jostling it around under your truck. They are easy to install afterward.

If you ever have your DPF back on your truck, do the opposite. Remove the sensors, remove the delete pipe, install DPF, install sensors. The first install is the hardest, but after that, it can really be done with one person.

As far as tuning goes, I think the Spartan system is coming out on top in every test I have heard of. The three tunes that I bought with the tuner were the 75, 150, and 210. That is a pretty good place to start. Then I bought the 275 later on, for $300. Also the nice thing about the spartan is that the dashdaq you use for the programming part also makes a really nice set of gauges. very sleek. I wouldn't want the SCT product sitting on my dash. Spartan's DashDaq has a good looking interface..

Spartan all the way man. They have the best proven power and reliability, and the gauge setup with the DashDAQ monitor and it's DTC reading capabilities are the best on the market. I don't doubt that Eric has some good/more improved stuff in the works, but at the moment Spartan is top notch. River City Diesel seems to be the closest to Spartan with tuning at the moment, but they are still not quite there. Plus the SCT Livewire monitor is not that great.

I bought the SCT9625OR and it came with the Powerstroker67 pipe. It took me about 3 hours of fighting to get it installed correctly. The pipe construction is awesome but they built it to tight tolerances and as such i had to actually slot the end so that i could get it to slip into my exhaust far enough to get all my hangers back on.

Anways, next time i think it would take me an hour at most.

I had no problems removing my sensors with a regular 1/2" wrench with everything was on the truck...but i believe 2 of them had been changed under warranty in the past 10,000km's. I also sprayed them with pennetrating oil the night before.

So that I would not damage the sensors taking the pipe out with them still installed, i removed them fully and left them plugged into the harness, then i just tucked them over the frame and out of the way.

Love my sct...picked up 2mpg on the first tank which was half stock 1/2 deleted with the SCT on Extreme and 1 full regen cycle at the start of the tank...and my speedo was reading 10% higher...thus my mileage was reading low....can't wait to see what the next tank will read with everything calibrated properly.
