Upgrades and Aftermarket - 6.0L EngineUpgrading or adding OEM or aftermarket equipment to your 2003-Up Super Duty or Excursion with 6.0L Power Stroke diesel engine. Please confine discussion of topics in this forum to those items that are specific to the 6.0L Power Stroke engine.
After much deliberation, I decided to go with the DPPI cat-back system on my truck. I called Mark and got it on order. It arrived right on time. I jumped right on it, thinking, based on what George C had said, that it would be a snap..... my mistake....taking the old system off was a real bear!(here's a hint for any considering the removal of the factory exhaust: get your hands on a sawzall, it'll save you a ton of time!). It took me almost an hour to get the dang thing off! Once I got it off, putting the DPPI system on was pretty easy. I'd say it took no more than a half hour for me to do it and I was working by myself. The pieces fit together very nicely and everything bolts right up. Fit and finish were great.
So... now I'm done putting it on. I anxiously stick the key in the ignition and fire it up, expecting to hear a nice throaty rumble...... well, I was a little disappointed to be honest. When it initially fired, I heard a real nice rumble, but that was followed by quiet. Maybe even quieter than the OE system. So, I blip the throttle, thinking I'd hear it then..... nope, only new noise was the turbo whistle. So now I'm a little bummed, though not bad, after all, I didn't want loud. (I was hoping for a little rumble though.) Anyway, 2 long highway trips later and YES!!!!!!! it now sounds just as I had originally hoped it would. I guess it just needed to get good and warm a couple of times to get there. As an added bonus, it still is nearly as quiet as stock inside the cab (you almost feel it more than you hear it, if that makes sense.)
Now I'm a happy camper and glad I got the system from Mark. I'd highly recommend this system to anyone who wants just a hint of the throaty rumble a big block gasser has, without the obnoxious roar in the cab. Thanks Mark!!!

It might be just a bit quicker accelerating from a dead stop, though that's strictly feel. I didn't buy a CC dooley to drag race, so I don't figure to really notice any gains until I tow and didn't have a chance to do that yet, so I can't really say. I also noticed an increase of about 2 tenths of a mile per gallon since the last time I checked it, but that may just be because I have about 2,000 more miles on it since the last time too.

TR,
It's the wrestling with the stock system that takes the time if one chooses to do so.
I didn't have a lift, so I cut off the tailpipe from the muffler.
It all fell apart in minutes.

That's what I ended up having to do too. I cut it right behind the muffler and then it came apart pretty easy. (I don't have a lift either, so I did all of this lying on my back under the truck. I also noticed it was much easier to do after I dropped the spare tire.) If I'd cut the thing with a sawzall from the get-go, it wouldn't have taken any time to get the factory system off, so those of you that decide to change yours out, take it from George and me, get your hands on one and cut that pipe right off the bat, it'll save you a bunch of time.
BTW George, I read your PM, thanks!

Yep it sounds that way a lot on cold engines. It's like Ford is using the VRT turbo to close the vanes just like they used the EVB on the 7.3's during cold or mostly cold start up to help heat up the engine quicker to lower emmissions etc. It really kills the rumble till the engine is at operating temp. Once the engine is up to temp it sounds real good, especially if you wail on the loud pedal. Glad you got her all buttoned up and call us if we can help.
The more I listen to it, the better I like it. It has a deep sound that just flat says to the world "I can move a mountain if I'm asked to". Except for the turbo whistle, the sound is almost more of a feel than a noise. It seems like you feel the deep note in your chest, more than you hear it with your ears, if that makes sense. I think it's way cool! You have to really listen to hear/feel it at all inside the cab with the windows up, cruising at highway speed, which is a plus if you are trying to listen to the radio or carry on a conversation. (Of course, if you go to WOT she'll talk to ya!)
I highly recommend this system to anyone who's looking to upgrade their exhaust. The installation of the DPPI system is a breeze once you get the old system off. The parts fit together like they should and it looks great once you're done.
Oh, and BTW, did I mention it sounds/feels way cool?? [img]/ubbthreads/images/graemlins/biggrin.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

Now the next question for Mark is when will a turbo back be available for an '04 - considering this apparent new turbo mounting bracket and downpipe design?
Mark, if you want to take a road trip North, I'll supply my truck for proper fit and finish refinments. At a small discount of course.

Well you have caught me off guard!! I haven't heard of a new turbo mounting set up etc. Fill in the blanks for me please, I guess I have been out in the south 40 or something.
Mark, according to the what's new for '04 brochure, the down pipe has been redesigned to cut out some of the turbo whistle and a bracket has been added to cut down on the drone noise when at certain rpm's. I don't think there is any physical change to the demensions are mounting of the turbo itself.
Mark, Spec. replied first, but to add: (It's a PDF file - may take some time to upload)
On top of page 19 of this What's New For 2004 Guide (page 20 of the PDF file), there is some information on turbo and downpipe revisions. I'm not sure if they're changing the downpipe dimensions, but it may be a possibility as they're changing the turbo mounting bracket and some angles, etc could be different.
Under the F-series trucks, starting on page 17 I believe, there is some info. on the new ICP sensor location, high pressure oil rail, etc. I don't know enough of the underhood space allocation for these parts to say whether or not their location change will change the turbo and downpipe placement even ever so slightly. However, one might be prudent to say there is a possibility....or not.[img]/ubbthreads/images/graemlins/shrug.gif[/img]
BTW, Mark, you could call it a holiday. Good hunting, fishing, and of course beer up here. [img]/ubbthreads/images/graemlins/wink.gif[/img] [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

Great info guys, thanks! Looks like the same system we currently have will still fit and operate like it does now. The turbo outlet and location look to be the same etc, but we'll have to keep a watch on ole man Ford to make sure. Also sounds like they are going to do what they did in late 1999 and ruin the turbo's efficiency for producing boost and possible start the surge problem that occured after the late 1999 turbo wheel change. Hope not but to quiet a turbo you have to change the blade pitch/blade quamtity and that in the past ahs reduced efficiency in the name of making it quiet. Hope I'm wrong, mine made 25 psi stock on the dyno!!!!
I agree Mark.
I had an early 99' with the loud turbo, and it ran much stronger than my buddy's 99'5.
Time will tell, but I believe those of us with the 03' turbo will make more power than the "improved' 04' version.
It will certainly sound better for those of us who are true diesel lovers.
My turbo will make a steady 28lb stock, and 30 while towing in stock mode.
Last week while running in the 115 mode (as usual) and towing, the turbo blew the hose off of the boost gauge inside of my truck. [img]/ubbthreads/images/graemlins/eek.gif[/img] [img]/ubbthreads/images/graemlins/eek.gif[/img]
Almost pooped my pants wondering what happened!
Over 30 lbs and pegged the gauge.
That must have led to the hose popping off.
Carefull George, You will be ordering head gaskets [img]/ubbthreads/images/graemlins/biggrin.gif[/img] Rick

I saw that some of the really crazy NOS guys have run 45+ lb's, so I think I'm safe..
