DPF back exhaust
2021 F250 6.7L - I have read a few other threads, but I can't find exactly what I am looking for. I kind of want to get an aftermarket muffler delete exhaust aft of the DPF. I was thinking about the Magnaflow option below. I won't be tuning my truck. Just replacing with this part. I want to hear a little louder exhaust and maybe hear the turbo spool. My question is, will this throw any codes without a tune? I'm still on the fence on this decision because I know it won't increase power or mileage and I don't think that will void my warranty.

the back exhuast only make sense if you go to 5" AND...you've done other upstream upgrades such as hi flow intake , hi flow turbo in and out piping, some type of performance controller, pedal controllers, methonal or nitrous injection......then maybe a performance gain but not by much ...typical DPF inlet pressure is about 2.5 to 3 bs above map and with the back exhuast you might pick up .25 to .5 reduction .
no change at all in sound.
if you want sound...get a siren speaker and run your favorite race car recording thru it as you will never get a varoom sound with a DPF/SCR.

I put on the MBRP system, its stainless steel, 4". I mainly did this for the look, I wanted the single outlet vs the factory twin outlet pipe. It offered nothing as far as performance goes (based on feel), but at $365 and free shipping...I'm real happy. And if I ever delete, I'm half way there, pipe wise.

But you won't get any codes and it won't void your warranty.

To the OP,.......... plan on purchasing a new Diesel Exhaust Particulate Sensor as the original one will most likely get destroyed upon removing it from the oem pipe (located at the over axle point). My new replacement sensor was $78 from eBay.

I will add that there is a small amount of sound added with the aftermarket pipe. At idle you cannot tell, towing heavy is when you can hear it. The oem pipe has a small resonator in it (over the axle), and it is there for a reason I don't know, assuming it comes into play with sound deadening while under heavy throttle (towing). And if this is the case then it also brings a slight amount of restriction (slight), so being gone perhaps the exhaust will flow easier........again I can't "feel" the gains if any.

mine had a nox sensor in that location and it would not come out.

Probably cost less than $100.
And, then MBRP makes some nice looking SS tip covers for the stock tips.
Here is my thread about doing the MBRP tips> https://www.ford-trucks.com/forums/1...aust-tips.html

"Liberates double digit horsepower"
One thing I know about Gale Banks is that he's a salesman and he'll tell you every time that his stuff is the best on the market. Take is with a grain of salt. I put his Six-Gun kit on my old '04 F350 6.0L. It was noticeable power increase but TBH not spectacular.

I'm running the MagnaFlow #17067 (Black version) due to it being 5" w/T409 piping. I run the full Pusher Piping kit along with a S&B open air element filter/intake. Truck runs great, sound good in the cab (more from the S&B and Pusher system), while not having any codes or issues.
The Magnaflow will not increase any sound out the pipe. I do feel the increased piping size has helped the motor breathe better. I tend to track my MPGs/fuel fill at every fuel up with the Fuelly app, noting nothing adverse but sustaining the running average. I've been trying to get into an active regen then fill up on fuel to get a track of the MPGs.
So far it's doing great running 500+ miles, getting the Active Regen done, then fueling up shortly after....seems to be holding pretty well over 17+ MPG with my driving. (Of course yours will vary).
So yea putting on a DPF back for any single reason might not be a good thing...but if you are doing more than one thing to the motor it's an easy YES.
