Hey guys, it's Sara with americantrucks.com and today we have a review and install the
MagnaFlow 4 inch DPF Series Single Exhaust System Side Exit. fitting your '17 through
'19 6.7L Power Stroke F250 and F350 Super Duty.
This off-road pro series DPF back exhaust will ad some improved sound and style to your
F250 or 350.
This exhaust system all around is larger than factory, it features 4-inch stainless steel
tubing with 5-inch cooled satin black tips.
I'm gonna give this exhausted 2 out of 5 on the loudness meter with the piping larger
and the resonator out the back illuminated, you will get some improved sound, however,
it's not gonna blow your eardrums out because the DPF is intact and that is the most restrictive
part of this diesel exhaust system.
Coming in at around $650, this is a great way to improve the sound and the look of your
exhaust without breaking the bank.
I'm giving this install 1 out of 3 wrenches on the difficulty meter.
It can be done in approximately two hours but it may require cutting of the piping on
certain models, so it could take some extra time to get the adjustability just right but
once you do this exhaust looks great installed.
For this install, we used an impact gun, a ratchet, 15 and 10-millimeter sockets, a 24-millimeter
wrench, a 10-millimeter ratcheting wrench, and an exhaust hanger removal tool.
All right, so the first step before we can remove our exhaust is to remove the O2 sensor
in the over axle pipe if you have a 67.
Now we hit this with a little PB B'Laster around the threads just to make it easier
on us.
So grab your 24-millimeter wrench or O2 sensor wrench and let's get this removed.
Grab this and hang it out of the way so it doesn't get damaged while we're removing our
exhaust.
All right, so at this point, we're gonna remove the nuts that hold our extension pipe to the
DPF and the rest of your exhaust so that we can remove it.
Grab a 15-millimeter socket, and let's get these off.
Next up, remove the nuts on the back of the extension pipe holding it to your exhaust.
So at this point, we're going to remove the exhaust hanger by removing the 5, 10-millimeter
bolts that are holding it in.
We're gonna start with the two farther up bolts, there's two that hold it on the backside
of this part of the frame and then we're gonna get these three underneath.
Using a ratcheting 10-millimeter wrench, remove these top two bolts.
Now, we can remove the three bolts holding this plate on underneath the frame, we're
gonna use a ratchet and also an impact gun with a 10-millimeter socket to remove these.
All right, so the only thing holding on the back tailpipe of our exhaust on is this last
hanger and we're gonna remove that now using our hanger removal tool.
All right.
Make sure you support those, you may wanna grab a friend for this step.
All right.
Now that we have our factory exhaust uninstalled from our truck, we can put it side by side
with our MagnaFlow exhaust, really check out some of the similarities and differences.
Now right off the back, you may have noticed the MagnaFlow tips are quite a bit larger
than factory, they do still feature a side exit configuration and cooling vents similar
to factory but they are 5 inches and feature a nice satin black finish.
Now the MagnaFlow piping is also larger coming in at 4 inches where the factory is three
and a half.
The MagnaFlow exhaust also removes that small resonator at the rear bringing some improved
sound to your power stroke.
All right, with that said let's get our hangers transferred over to our new exhaust.
All right, so we do have to remove the two hangars at the front of our factory exhaust.
We can reuse these for our MagnaFlow.
Using your hanger removal tool or by hand, work it towards the front of the hanger.
And repeat that with the other one.
All right, so we're gonna bolt this exhaust hanger bracket back onto the truck to make
it a little easier to install our new exhaust.
Using a 10-millimeter socket tighten these down.
Using a 10-millimeter ratcheting wrench, tighten down the bolts on the frame.
All right, so the first step in our install is to mount this flange up to the back of
our DPF.
Now, it is worth noting you'll have to reuse the factory gasket here because one is not
included, but if you'd like to purchase one you can do that and put it on yourself.
To line up the flange with each of the studs.
Grab the factory nuts, and thread them on.
Grab your 15-millimeter socket and tighten these down.
All right, so we have our extension pipe here and depending on the model of your truck you're
gonna have to cut this the different lengths to fit.
We have our crew cab short bed 67, so we're going to have to cut this 26 and a half inches
which we've marked here and that is a measurement of how much gets cut out.
Make sure that you're cutting towards the far section and not the section that's notched
so it can fit to the rest of your exhaust.
So with our mark made, let's cut our extension pipe.
All right, so we have the extension pipe piece that we just cut.
We have our over axle section, we're gonna join these now because it will be a little
bit easier than doing it on the truck.
All right, now we can work it over the axle. all right, we have our over axle pipe right
here for now.
We're gonna put our clamps in place and then we're gonna get these attached.
Slide the first clamp over the flange end.
And we're also gonna slide our hanger clamp over the flange end, for now, to keep it in
place.
Slide your third clamp over our pipe section.
And now, we can lift our pipe in place.
This one we can push up on the exhaust and get the hangers installed.
All right, next up, we're gonna slide one of our clamps over our over axle pipe and
let it hang out up top so we can get our tailpipe installed.
Next up, slide the hanger clamp over your tailpipe section and get this in place.
At this point, with your tailpipe supported, line up the hanger and get it installed.
Once that's in place, let's tighten down our clamps.
All right, starting at the very front-most clamp, get it in place and with a15-millimeter
socket tighten it down.
Next up, tighten down the hanger clamp and then the next clamp in line.
Finally, tighten down the clamps holding on your tailpipe and the tailpipe hanger.
All right, at this point, we can put our O2 sensor back, but before we do that, we're
gonna put a little bit of Anti-Seize into the threads on the bung of our exhaust.
This should help if we ever have to remove the O2 sensor again.
Grab the O2 sensor from where you tucked it out of the way, line it up with the bung and
get it started.
Grab your 24-millimeter wrench and tighten it down.
Make sure you tuck away the cable at the end of your O2 sensor to ensure it doesn't move
anywhere.
All right, that is gonna do it for the review and install of this MagnaFlow exhaust.
