Bottom line on DPF/EGR deletes....

[Drbrodent]

So I have read and read and read and I am pretty sure I have my info right but I just want to bottom line it here. Basicly if you leave the stock stuff on you are lucky if you dont end up having problems, turbo, early oil changes, etc...even more so if its your daily driver, sound about right? I have no idea what the history of the truck is, its an 07.5 I bought with 65k miles on it two months ago and so far so good. I am not so much looking for more power (but I dont mind it lol) but I am worried that if I dont do some deletes I am going to end up having expensive problems. So I unplugged my EGR last week, and was planning on doing the EGR and EGR cooler delete right away as it seemed like the cheep and easy way to start. Well now in more reading I am pretty sure I understand that you shouldnt do anything with the EGR without doing the DPF delete first, is this correct? I am coming to the conclusion that I just need to bite the bullet and order both if I really want true piece of mind! So that brings me to my last question I am looking at an H & S 4" basic delete, I see they have a stage two that comes with a new 4" down pipe for another $100, is this worth the extra money? And has anyone installed the H & S kit? Is it really plug and play no welding...just seems to good to be true! I know you guys see us newbies keep asking the same questions but I have honestly read and read and read, any answers any of you are willing to throw my way is greatly appreciated!!!!!

Yes you are right - you cannot do EGR delete without doing the DPF delete atleast what I understand. And without the deletes your DPF & CAT filters are going to be plugged often and you will get CEL messages and limp mode and shorter engine life and all that kind of stuff...

I have the H&S kit with the downpipe. I believe that's the way to go because it gets rid of the CAT filter in the downpipe as well. Almost all of the guys in the forum has the stage 2 I believe.

If I am not mistaken there is a post in the 6.7L articles section of the forum where you can actually make a DIY downpipe and delete kit. If you are good with things like that you can do it yourself, if you have tools for cutting etc. I assume. I haven't looked too much into it since I knew I wasn't going to be able to do it myself..

I think you still need a programmer to clear codes after the delete because it will throw a soft code. I don't know if H&S has worked this out - I got my kit a long time ago... and there have been many updates since then.

You can do all the install yourself. It will take couple of hours. No welding/drilling. Everything is bolt on. You may need an extra hand because the stock exhaust is so heavy and it is a pain to take the down pipe out...

I bought my truck 29K miles used... had to make a few trips to the dealer in the first couple of months, decided to do the deletes -now it is sitting at 55k miles and have not had any issues. Probably never going to see the dealer again...

the stage 2 is definitely worth $100 if you havent looked yet there is a resonator in the down pipe that is very restrictive if ya dont get the new down pipe your not gonna get the effect your looking for. Best bet is to do the deletes all at once and look at getting a tuner for code free H&S has the great XRT and there is the SMARTY

unless you just want to do homemade sims and live with the possible CEL

A couple of hours for a stage 2 delete? You guys kill me. Maybe if you have your' own shop! It took me an afternoon and I had to send the wife out for more beer. I don't run a tuner yet, and the codes are not a problem. They are all soft. The only thing you will see is the CEL for unplugging the EGR. The electronics are plug ins in place of the temperature sensors to stop the regens. I love mine, noticeably more power, got it from James.

You are mistaken. With the EGR deleted or unplugged there will be less soot into the turbo as well as out the pipe. There are several threads with numerous owners that have run that way for thousands of miles. I personally put over 6K before I did my DPF deletes. With the EGR unplugged it causes a CEL and a P0405 code. With that code the ECM doesn't even attempt to use the Butterfly or the egr related stuff. I experienced an increase in the miles between regen by near 30% from every 150 to every 250 miles. MPG's increase. Trips to the dealer are reduced to near nothing. I've never been to the dealer, except for something stupid that I did to the truck. And they were nice enough to cover that under warranty.

A person with mechanical aptitude can do the TBE in about 2 hours with a helper. I couldn't imagine doing that job single handed. It takes a person holding the pipe in position to put the turbo clamp on.
Look in the Tech article section. Link in my signature for all kinds of articles on the DIY deletes and EGR deletes. What WORKS and what doesn't. There a wealth of real time experience in that section.

Two people is nice. A hydraulic lift in a shop is nicer, or you can shim the downpipe to the tranny crossmember, snug the clamp and then reposition when the entire exhaust is loosely installed.

Dad2bike.. I didn't know that.. sorry for the wrong info and thanks for correcting...

I was out of the forum for a while from about January through May and I probably missed a lot of information. I know when it all started some people who tried to block the EGR without doing the DPF delete were having some issues... Anyway it is good to know.

BTW, with the EGR blocked and DPF still intact, how was the economy? Did you gain any MPG? Was it as good as with the dpf delete?

EGR just unpluged not even blocked I gained about 1.6 MPG hand calculated and got better throttle response and low end. Less heated exhaust returned to combustion chambers = better burn with the cooler air

what kind of MPG do you get now with the Smarty?

Hey thanks for your input guys, after what you guys have said and all the reading I have done I quit hesitating and called James at Rolling Smoke....the guy is a stud, he took the time to explain some things and answer every question I could think of! Ended up on his website last night and ordered the stage two kit as well as the full EGR delete kit. Looks like after next weekend I wont have to worry about this stuff anymore! Also ordered the 2" kit from Hell Bent Steel....I just hope I can do all three projects in one weekend! Thanks again guys...and a huge thanks to James.

I just got my smarty last night I only have like 45 miles on it and trust me those wont be the ones that saved me any fuel. The new will have to wear off of it a bit then I will behave myself and check that
