I have a 2007.5 3500 6.7 with a manuel tranny......my question is there anybody that has eliminated there muffler, cat, and dpf on a 6.7L . .? if so what were the gains ? any problems..? any problems with the computer..? also i live in california so i know im not supposed to remove any of the smog crap but ....for the sake of conversation....of course.

The amount of gain, (Hp & Torque) compared to the amount of headaches your going to indower (meeting emissions requirements)
I don't think it's gonna be worth it.

You will see a big improvement in HP gain and Fuel Mileage if you delete the DPF.

I unplugged the egr and I am getting about 18mpg around town and I have the 6 speed manual too. After I unplugged the egr the truck has a lot more power and shifts a lot smoother. Ive only had it unplugged for a week so i have not ran into any problems, but yet i hear both sides that it is good for the engine but yet bad. Anyone here think its bad to unplug the egr or to even bi-pass the dpf?

You have to have programmer to delete the DPF or the EGR correctly.

But what are the consequences of unplugging the egr and keeping the dpf

After a bit you will get a check engine light because the computer will see no signal from the EGR Sensor.

Yeah that came on right away, but idk maybe it is me but random times after driving about a hour it sputtered at idol once and didnt anymore? I figured it was a burp

I would honestly just get a programmer and delete the DPF

My 2 biggest concerns are 1. I dont wont to have any mechanical headaches/problems from removing parts. 2. Because i live in california i have the smog crap to deal with.......maybe i will go find a " pre-smog" diesel and just go nuts out with that ........
