Going to delete - looking for muffler guidance

As the title states, I am looking to delete. I actually want the truck to look stock (to the casual observer), so I prefer to keep the stock exhaust tips (I know some folks will bristle at that). I am wondering if I should just keep the last section of pipe that connects to the stock tips? Is there a resonator in that section?

I want to use a Donaldson 51" (but can be convince of something else if simpler). I have found the part number. What else should I purchase to make this work? Do I need to custom fabricate hangers? Do I need to do something about flanged ends? Do I need to order hangers or clamps or? I am looking at 4". I guess I prefer stainless but aluminized is probably fine (I guess the donaldson is aluminized, correct?). I am curious if the Flo Pro system with muffler sounds comparable? I see so many options (for example on Rudy's site) that I am confused.

I am curious if anyone has a setup like this and can point me in the right direction for part numbers for what I need or make some suggestions?

Thanks. I searched and found some information, but not anything that listed what I would need to make this system work. Sorry for so many questions...

You may want to research installing a DPF delete pipe and not a full exhaust. Something like this AFE ATLAS 4" Aluminized Cat / DPF Delete Pipe 11-14 6.7L Powerstroke looks like you would only need to cut in a muffler of your choice. It appears to have the flare on the front end and a flange on the rear. Should be pretty simple if that is all it takes.

I did exactly what you are talking about. Order a 51" Donaldson muffler and a DPF delete pipe (one that comes in two pieces). Remove the DPF. Install the front piece of the two piece delete pipe (attaches directly to the stock down pipe). The Donaldson slides right on to the end of that piece. Now all that's left is to measure and cut the 2nd piece of the delete pipe to install between the muffler and the factory tailpipe section. You'll need a couple of 4 inch clamps. I didn't have to add any hangers or supports and it's solid.

I did this and it looks completely stock except for the soot on the tailpipe. The sound in the cab is close to stock. The sound outside the truck is louder, but nothing too loud.

If someone wanted to PM with where to buy, what part numbers, etc I'd be appreciative. Deerhunter, it seems you have exactly the setup. Also, are the tunes you're running superior to H&S canned in your opinion? I am really looking for a good daily driver, better mileage if I'm easy on it, and longevity. I do tow once in a while.

Also, I am trying to decide on block off plates or full delete on the EGR. And what about intercooler pipe? Are people changing those out as well? Thanks!

Does the Donaldson muffler come with clamps? Just ordered the 40" and forgot about needing a muffler clamp.

No. My 51" didn't. You can get the cheap clamps at autozone.

No they don't come with it I just put my 40 on last week. If your doing the 4 inch pipe the clamp p/n is 20400ES they are stainless you need two of them If you just ordered it you should be able to call them and have them add them to your order.
