Hey, guys, this is the Mac Dual Exhaust Conversion Kit for the 2005 to 2010 V6 Mustang.
You're gonna wanna check out this kit if you're looking for a dual exhaust conversion kit
for your V6 that'll keep the factory Y-pipe, give you four-inch tailpipes and you're looking
to get a good bang for your buck.
The MAC Conversion Kit is currently one of the more affordable dual exhaust conversion
kits for the V6 with a price tag of about 570 bucks.
It has two and a half inch aluminized tubing to four-inch polished stainless steel tips.
The install for this is something that we'll go over in more detail in a minute.
But you can expect it to take you about two hours, and it's a two out of three wrenches
on the difficulty meter because you will need to cut your rear bumper to fit the new exhaust.
I'll say right away that I'm gonna call this system a two out of five on the loudness meter.
It's gonna make for a notable change in exhaust tone.
But you have to keep in mind that you are keeping your stock Y-pipe with all of your
stock cats still.
When you go with a setup like this one, you can only get so much change in sound.
Don't get me wrong though, it is louder than the stock system without a doubt.
And the other nice thing about this is that these are stainless steel four-inch tips.
So you get the nice look out back under the rear bumper.
This system comes with a mac flow path chambered mufflers.
These mufflers don't have any packing in them.
They have a multi-passage design and that's how they get their sound.
The good thing about having mufflers with no packing is that the sound won't change
at all over time.
It'll be consistent all of the time since there's no internal packing to burn out.
You don't have to cut the stock mid pipe.
This actually bolts right up to the stock Y-pipe.
You don't even have to pull it off of the car.
You're literally just bolting this on and going.
One thing I'll add here is that you will need to grab an additional exhaust hanger kit.
You can do so through the drop-down menu on the product page or you can pick up a hanger
kit yourself.
Either way is fine.
You'll just need that new hanger kit for the new additional muffler since the V6 only comes
with one from the factory.
And keep in mind that you might need to modify your rear bumper to fit that other exhauster
tip.
If you didn't wanna cut your stock bumper, you could always pick up a GT bumper, but
most people just modify their factory bumper.
The install for this system is a two out of three wrenches on the difficulty meter because
you will be cutting that rear bumper.
You can expect install to take you a few hours, about two to three, and we'll send you guys
over to an install bay now to show you exactly how it's done.
All right.
Now that we have our car up on the lift for this install, we're gonna start off with spraying
everything down.
Our car has a couple of miles on it.
Yours probably does too.
So go ahead and hit all those hangers and all those nuts and bolts with a little bit
of PB Blaster or WD-40.
All right.
So with everything oiled up, the first step is removing the factory muffler right here.
It's held on by one rubber hanging and isolator and then you have this clamp right here holding
it to our over axle pipe.
Now, our clamp here has definitely seen some miles.
Normally, we'd be taking this bolt out with a 14-millimeter socket.
It's already loosened for us.
However, this clamp is a little rusty so I'd recommend a big old pry bar so you can pry
this clamp open and pull the muffler off the flow tube.
All right.
With the clamp connecting our over axle pipe to our muffler loosened, it's time for us
to get the muffler itself off the pipe.
Now, again, if your car has seen some miles, it might be seized up pretty good.
So you're gonna have my two favorite tools, a mallet, and a pry bar to try and get some
leverage and tap this thing loose.
All right.
So we tried to pull our muffler off our over axle pipe, but our worst fears were confirmed.
It's a little bit too rusty.
So we need to get a little bit of leverage.
Now, there's an easy way to go about this.
You can actually remove the rearmost hanger on the muffler.
It's gonna allow you to drop it down and twist it free.
There are two bolts up here on this hanger.
They're supposed to be 13 millimeters.
If rust and age have eaten away at them a bit, you can step down to a half-inch.
So we're gonna go ahead and remove that hanger now.
All right.
So with our rear most hanger removed back here, we actually have a lot more play on
our muffler now.
The last step to freeing the muffler up completely is to pull the muffler hanger out of this
isolator up here, pretty simple once you have the rearmost one removed.
Just take a pry bar, push it against the rubber isolator, and you should be able to push it
out as well.
All right.
So with that second rubber isolator freed up, now you should have enough leverage to
pull your muffler out.
There's still one more hanger back here, but it doesn't have that bulb end on it.
So the actual metal piece should slide in and out pretty easily.
So, at this point, it's just a matter of using some brute force to get that muffler off that
over axle tube.
So with our muffler removed, it's time for us to remove the over axle pipe/flow tube.
It's held on with this clamp right here and you got two 15-millimeter bolts securing it.
All right.
So, as has been the case with our install thus far, these are pretty rusted and seized
up.
Now, our 15 kinda has started to strip a little bit so we backed off.
We're gonna step down to a 9/16 and that should do the job.
With those bolts removed from our clamp, it's still seized up here pretty good.
So we're gonna hit it with some penetrating oil and then we're gonna take our pry bar to it, that way we can open it up a bit and this pipe should slide off the Y-pipe.
All right.
So now that we brute forced our stock flow tube off of our catback here, we're gonna
go ahead and take the AccuSeal clamp off, and this is the only part that we're actually
gonna be using with our new exhaust system.
Now, I highly recommend you take some wire brush or maybe some steel wool, definitely
take some penetrating oil and clean out inside of this clamp, that way it slides on nicely
to the original pipe and the new pipe.
All right.
So our stock catback is off the vehicle and we know we're free and clear to install our
new catback.
But before we do that, we have to cut into our bumper cover.
Obviously, you know that the factory V6 only comes with one cut out.
It's very easy to do the second cut out here.
You can find a template online.
That's exactly what we did.
So we're gonna go ahead and mark ours up with some permanent marker and then we're gonna
go ahead and start cutting.
All right.
So now with our template marked up, here, there's a couple of ways you can cut into
the bumper.
You could use a die grinder or a Sawzall.
But honestly, an air saw like this, which goes at high rpm is gonna give you the most
control, and it's gonna cut slowly but consistently.
That way you make sure you have a nice clean cut that you can polish up later.
All right.
Now that we have our whole roughly cut out, we're gonna go ahead and polish it up here
with one of our air Dremels.
Now, as you saw, I cut a little bit less than I needed to, that way when I polish it up
with this, it's gonna be the perfect size.
Won't have any of these burrs or little nasty crusty bits on there.
All right.
So, with that whole polished up, if you have any leftover marker, just go ahead and take
some rubbing alcohol, that'll come off very easily.
As you're polishing that up, just take your time kind of benchmark against the other hole
there.
And you should be able to notice pretty easily if it's the same size or if you need to take
any bit extra off.
Now, that's all set up.
So we're gonna go ahead and start installing our new exhaust.
All right.
Now, it's time for us to start installing our exhaust like I mentioned earlier.
We're gonna go ahead and reuse that original clamp, and we're gonna grab our MAC Y-pipe.
Now, when you install a Y-pipe, you wanna make sure that the bends go towards the driver
side, that way it's gonna clear your drive shaft.
All right.
Now that our MAC Y-pipe is bolted up to our original Y-pipe, you might notice that there's
a little bit of clearance right here missing.
It's touching the drive shaft right now.
That's okay.
We don't have any load on our rear axle.
So, yes, when you install the MAC Y-pipe, you will be very close if not touching the
drive shaft directly.
We just lowered our car to make sure that it clears and you have plenty of clearance.
So do not worry about that.
The next step is getting the over axle pipes installed.
All right.
The next step is grabbing those over axle pipes like I mentioned with one of the provided
clamps.
I'm gonna start off with the passenger side because our hangers are already set up.
When you grab the over axle pipe, the pipe itself is going to flare outward towards the
wheel.
That's how you'll know which side you're grabbing.
The flared end here is gonna fit on to the MAC Y-pipe.
All right.
When you get the over axle pipe onto the MAC Y-pipe, you don't wanna tighten down your
clamp just yet.
You wanna keep everything loose.
That way when you go to fit your muffler onto those hangers, you'll have a little bit of
room to play around.
All right.
Next, we're gonna grab our passenger side muffler and we're gonna go ahead and bolt
it up to our over axle pipe that we've just installed.
Now, to make it easier on yourself, I'd go ahead and spray down the rubber isolator that
the muffler hangs from, and I'd also spray the end of the over axle pipe.
That way the flared end of the muffler will slide on a little bit more easily.
All right.
Now as you hang this, go ahead and put one of your clamps on the end of your muffler
and slide it into the isolator.
Once it's slid into the isolator, grab your over axle pipe and slide it into the flared
end of the muffler and keep it hand tight for now.
Don't tighten your clamp down.
Wanna make sure we get everything in place first.
All right.
Now with our muffler hung and in a good spot, we're gonna go ahead and reinstall the bracket
that we originally took off for the rubber isolator.
All right.
So our passenger side is all hooked up and our hanger is reinstalled on that side.
Next step is installing our driver's side over axle pipe.
All right.
Now that our over axle pipe is installed, it's time for us to put on the driver side
muffler.
Now, because of the way the driver side over axle pipe connects to the muffler, it's very
difficult to install the hangers first and then put the muffler on.
We've been trying out different methods here, and it might seem a little bit difficult,
but the easiest way to do this is to actually hang the hangers on the muffler, hook it up
to your over axle pipe, and then while you're holding the muffler in place, just go ahead
and hand tighten some screws into the hangers and you should be good to go.
All right.
So with your driver's side muffler hung up with those new brackets, it's time to actually
tighten everything down.
Before you do that, go ahead and go over all the piping.
Make sure nothing is touching the car itself, that way you don't get any vibration or drone
when you're driving around.
Once you've verified all that and you like where your mufflers are sitting, go ahead
and grab a 12-millimeter socket and hit all the clamps that we installed earlier.
All right.
So with those clamps tightened down, that actually wraps up our review and install of
the MAC dual exhaust conversion for '05 to '09 V6.
I'm Travis.
Thanks for watching.
