Today we're going to show you how to add a killer exhaust and an almost 30 rear wheel horsepower to your stock 2015 to 2017 Mustang GT with help from Roush Performance.

A cold air kit exhaust and tuner without a doubt the three most popular modifications Mustang owners make to their cars. Roush makes the decision very easy by offering all three in their Level Two performance pack. It's gonna include the Roush cold air intake, which will be a direct replacement for your factory intake along with the Roush axle back and this custom tuner that's gonna work with your 2015 through 2017 Mustang GT. The Level Two power pack starts off with their cold air cable, which will be a direct replacement for your factory air box to provide more flow to the engine. Also have a lifetime reusable air filter. The exhaust is Roush's popular axle back, which will fit the 2015 through 2017 GT and it's made of 304 stainless steel with 2 1/2" piping and a set of Roush 4" chrome tips. The system combined with the custom tune provided by Roush can provide 29 rear wheel horsepower and 36 rear wheel pound feet of torque.

For this installation, you'll need a lift or a jack and jack stands, 1/4" ratchet, 7 millimeter socket, 8 millimeter socket, 10 millimeter socket, 3/8 ratchet, 15 millimeter socket, T-20 Torx bit, marker, sawzall, safety glasses, a file, and a Windows based laptop computer.

So to begin the installation, the first thing we're gonna do obviously is remove our factory cold air intake kit. We'll start by removing the intake cover just to give us a little more room.

Here, you just simply pull up. The factory air intake can actually come out in one piece. First thing we're gonna do though is disconnect everything from it, the mass air sensor and all of our airlines.

We just push in and the gray tab, push the tab to the side. Then here's a little red tab underneath. Pull that out and squeeze. Don't forget to remove the clip from the air box. Then we're gonna disconnect the hose clamp at the throttle body.

Remove that and then the last step, remove this bolt over on the fender.

All right, now you can remove the whole thing as one piece. I should mention our sound tubes are deleted. You can remove that with a hose clamp and the inlet that's also been removed.

We'll need a few stock pieces from the intake. This is the easiest one to lose though. A lot of the times, this will fall off. Once you just pop this off, put it back in the fender where it came out. Another piece from the air box we're gonna need is going to be this rubber grommet and typically, there's actually gonna be a metal insert. You push the metal insert out first and then you can remove the grommet.

Then the last part we need from the factory air box is the mass air sensor.

You'll begin the Roush installation now with the cold air kit and we'll start by taking this grommet. Put it in the opening right here. And like I said, the metal insert, we go in from the top. You're gonna connect the air inlet to the Roush box.

Just line it up. It'll pop into place.

Okay, then the assembly can go into the car.

You can reinstall this screw in the fender area.

Okay, now that I've got the mass air meter along with our filter, put the filter on with the metal downward and tighten it down. Now we'll put the whole assembly into the air box and install the provided screws.

With the housing installed, we can install the mass air sensor next. Now it'll only fit one way. But as a trick, you want the black side facing up, the chrome side here facing down. Then reinstall with the original screws.

All right, now the last step here is to install the intake tube.

Once they're in place, tighten them down.

Now we're gonna reconnect all the fittings. Now if you have a 2017 Mustang or some even in the late 2016s, you will not have a hose to go here in which case take the supplied plug. Just put it over the top. On the 2015 and most 2016s, that small one will connect there and the large one goes underneath.

Now the last step's the plug in the mass air sensor. What we gotta do is remove this little white tab right here and there's another one right down here kind of behind the air box. Pull that off. That'll leave you some slack in the wiring.

Then you come in behind the air box over here. Fish it over and then plug it in.

The installation for our cold air kit is complete. We can move on to the exhaust. While we're under the hood, the first step in the process of actually tuning the car, you'll need the computer code. You can see it located right here on the computer, that four digit code, in our case, RMJ3. You'll want to write that down. You will need it later. With the cold intake installed, now we're ready to work on the exhaust system. Now the axle back will require cutting. When you follow the instructions by Roush, what they tell you to do is to cut the pipe at the tangent of the curb. Now if you're like me and forget geometry and have no idea what the tangent is, don't worry. I had to look it up as well. The tangent is basically the flat part right at the beginning of the curve. So follow the curve down here and it gets flat. You'll actually even see, there's almost a little seam here. This is where we're going to cut.

Once you have it cut, make sure there's no edges here. If there are, just clean everything up. All right, now we're gonna grab the Roush muffler. They are side specific. Make sure you grab the correct one. Start by putting it in the rear hanger first.

Line it up and slide it on. Then slide the clamp over and we'll snug it down for now, make our final adjustment later.

All right, then grab a 4" chrome tip. Put a clamp on that. Slide down the muffler. Get it straight. Then tighten it down.

All right, tighten everything up and you'll repeat the process on the other side and we can move onto the tune. We're gonna fire it up. We'll show you how the Roush exhaust sounds. It adds a real nice rumble to the factory exhaust by just doing the axle back and if you wanted more, Roush also makes a resonator to lead. With our Roush performance parts installed, now the next step is going to be the tuning process using the supplied cable along with your laptop computer. Now the Roush performance power pack gonna provide excellent horsepower and torque gains along with gains across the board. If you want to make sure to get optimum performance out of it, you have to run on at 91 octane fuel and make sure the car is in sport mode. Okay so now onto flash the vehicle, the first thing you're gonna do is go to our website and download some software. It's RDT.roush.com. You can fill out the information. Then on the bottom, click Submit. There will be a user agreement that's gonna pop up next. Go down to the bottom. Click Accept and Submit.

Okay, what you're gonna get, this is very important, you're gonna get an activation code. You want to make sure you write that down and save it because you will need it. Now this should be at the bottom of your screen. But if not, just go in your Downloads folder. You're gonna double click. Then it'll walk through the installation.

To complete, you're gonna finish.

Close that. Than you want to grab the supplied disc. Put that in your disc drive. We're gonna load that next. Again, that should load automatically. Then install the software on the disc. Then close out of this. Then right on your home page here, your desktop, the Roush diagnostic tool. Click on that. All right, so then this page here, now you're gonna type in your email address then at activation code we wrote down earlier. All right, once you put the name and password here, this screen should come up. If you get a screen that says, "Error," or "Not Connected," I should have mentioned earlier, the original website we went to, it was the RDT.Roush.com, you need to leave that up in the background because program will be drawing information from that website. Okay now at this point, you're gonna take your laptop and you connect it to your vehicle using the supplied cable. Plug this cable in the OB2 port. What you're gonna do is just basically follow the headlight switch down and it's right here under the dash, kind of where your hood release is. Plug that in. Connect the other end to your computer.

Okay, once you get the devices ready, you're gonna hit the ignition button on the car. With the key on, you're gonna select the device, which is the dash bridge cable we just connected and then click vehicle ID. All right, so once you click on vehicle ID, this should come up. Make sure it is the correct year of your car and make sure the VIN number is correct. If you're not sure about the VIN, it's right inside the windshield on the driver's side in the front. What you'll do next is go down here to Module Programming. Now this voucher will be included with your power pack. What you're gonna do now is go on the back and enter this code.

You'll start with the code, then the voucher family is on the front. We'll click Redeem. Once you have the voucher family, the last step is the tear tag. Now what that is, that's the four digit computer code from under the hood that we wrote down earlier. Once you get everything, click Redeem Now. Now if you did everything right, it's gonna redeem the code and say, "Redemption Successful and Flash is enabled." Just hit Okay and then you go right down here to flash the car. Now basically what you're getting is you're basically getting a warning here. You're saying make sure that everything's plugged in like it's supposed to. Make sure there's no accessories running. Make sure everything is good to go. Your battery's good. We're gonna hit Okay. Turn the key on. Hit Okay and that's gonna begin programming. Now this process here, you're lights are gonna flash, beeper's gonna go off. You're gonna see all kinds of things happening with the car, all perfectly normal. Now here is actually a programmer. You're gonna see the green bar's gonna move across and the first time you do this, it will take some time.

I've seen it take five, even 10 minutes on the first tune. But as long as you're getting progress, you're good.

Now here you can see you're getting a Cycle the Ignition code. So you're gonna turn the ignition off and then back on and when you're done, you'll get a Flash Complete then click Okay and you can disconnect the module. All right, so once you're done flashing the car, now the last step of the installation, start it up. Make sure everything works like it should.

And your installation's finished.

Like I mentioned earlier, a cold air kit exhaust and a tune is one of the most tried and true ways to make horsepower with your S550 Mustang. Roush takes all the guesswork out of it with their power pack Level Two, which gives you the exhaust cold air kit and the tune to tie it all together. It should provide excellent horsepower across the board. The installation is very straightforward. Figure about two hours total. You'll be back on the road in no time.
