exhaust system. cat/dpf

[Bryce18]

On the 6.4 the dpf is bolted between the cat and tail pipe, but on the 6.7 it looks like its all combined. Does they dpf unbolt from the cat? I couldn't see where it did anywhere. Im getting ready to do a dpf delete and I could use some help

Its all integrated into one with the dpf. There's only three parts to the whole exhaust. They include the dpf which connects to the downpipe, a foot extension pipe, and the over axle part which is connected to the exhaust tip. You can either go with just a dpf delete and keep the rest stock piping or go with a full exhaust. If you go with a full exhaust I recommend Mbrp or Flo Pro.

Thanks a bunch. Do you have a dpf delete? If so could you post some pictures from underneath your truck. Id like to see what it looks like installed.

A lot of people are just going with the DPF/Cat delete pipes as it is very easy to install. Below is a pic, you can see the glanges it uses for install, a direct bolt-in.

Installing the last new delete pipe wont be a problem, removing the dpf filter seems like the hard part.

I have a full exhaust so I don't know if you want a pic of that. The easiest way to uninstall the dpf is unplug all of the sensors first(there's about 5), then unbolt the exhaust hangers from the frame and drop it down. Dont worry about pulling the exhaust rubber fittings off the hanger while under the truck because that would be a pain. The dpf weights around 150lbs so be careful, you might want a friend to help or put a support under it.

Thanks a bunch! When unplugging the sensors, do I unplug from the dpf and leaveI on thethe truck, or unplug from the truck and leave the sensors on the dpf. And its easier just to unbolt from the frame then trying to take it off from the rubber fittings? And ya im planning on having a friend help.

Unplug the sensors on the dpf then unbolt the exhaust hangars and drop it down. Then once you have everything out, you can decide what to do with the hanging wires.

That sound pretty easy. So the sensors are no longer needed perfect! Now I just got to make some more money so I can by a h and s mini max and delete.
Thanks for the help!

Just to clarify brandonlee's post, nothing unplugs from the DPF/CAT/SCR. All the pigtail remain on the part your taking out. They all are about 1 foot long with the exception of the rear most plug, which is also the largest, it's about 2 foot long with a big plug end. Be very careful to get all the wire unplugged because when you get ready to drop it, it will yank anything out that's still plugged in and damage it. I'm dealing with that now. Also, the skid plate that protect the actual DPF portion comes off with 4 13mm bolts and makes it much easier to get the dang thing down. The 5 exhaust hanger nuts are 13mm, the 2 downpipe bell flange bolts are 13mm and the rear flange has 3 15mm nuts. Don't loose the shim/gaskets on the rear flange. It also help to put a ratchet strap around the over axle pipe and pull it straight back to get everything out easier. Good luck.
