Product Description

MagnaFlow Stainless Steel 3" Competition Series Cat-Back Exhaust Kit for all 2015, 2016 and 2017 GT Mustangs.

The stock exhaust system on your 2015-2017 GT Mustang works well, and it even gives you a nice muscle car roar. But when you really want the best in performance, efficiency, and volume, the MagnaFlow stainless steel cat-back exhaust system delivers what you want and then some.

This MagnaFlow exhaust system includes bolt-on parts that use the same mounting points and brackets as your stock exhaust, which makes it a breeze to install. And because it’s loud, it’s also a great way to show off the V8 that you have under the hood! Looking for a way to make your 2015-2017 GT Mustang sound as fast as it really is? This Stainless Steel 3" Competition Series Cat-Back Exhaust Kit from MagnaFlow is going to provide the aggressive, head-turning roar that you're looking for.

MagnaFlow Cat-Back Exhaust: Loud, Powerful, Easy to Install

This MagnaFlow cat-back exhaust system uses a free-flow X-pipe mid-section to safely siphon exhaust away from the engine while delivering a deep, satisfying roar. The 3” pipe sections offer a lot of space for your exhaust to flow, giving your pony car better performance and a sleek, efficient system to match. The end tips cap off your exhaust system with a smart, sleek, and modern appearance as well.

The MagnaFlow cat-back system comes with three durable and reliable pieces that you can quickly install on your pony car. The pipe sections slide on to stock hangers and sleeves easily.

MagnaFlow Cat-Back Exhaust Kit Competition Series 3" Stainless Steel GT 2015-2017 is rated 4.4 out of 5 by 11.
Rated 5 out of 5 by from BEST OLD SCHOOL SOUND EVER The video does not make justice to this exhaust set up. Personally it sounds much better in person. It gives my 2015 GT the old school sound, loud enough but not exaggerated. Deep, beautiful, wonderful and even romantic (it reminds me my teenage years) mellow sound. No raspiness at all. It gives a strong sound in low rpms, which I love. However, when you push it, the sound is strong but not exaggerated, like when you push the borla attack (my former set up). It does have a drone on cruising rpms, between 1900 to 2000 rpms, and I love it. I like to feel the engine when I'm driving on cruise speeds and when I am changing gears. You do loose a little of torque with this set up but you do get more horse power, what is expectable since it is a straight through exhaust, and you get rid of the resonator. I only noticed it, I had never had it measured. Overall I couldn't be happier, maybe if it were a little louder on high rpms, but it is what it is, just its own characteristics.

Rated 1 out of 5 by from Great build quality, but drones like crazy Installed on Friday, went back to stock on Monday. On the car 2.5 days, less than 20 miles. This is absolute worst droning system on the market (may not be, but I can't imagine one worse). Make sure you have Advil in the car for the headaches you will have. The frustration is that this is 2015...drone should be a thing of the past, it can and is engineered out of some systems. I call this engineering negligence on behalf of Magnaflow. If you have a 6 speed, the drone can be managed with downshifting/up shifting to stay away from the 1900-2200 rpm range...but those of you with automatics...your family won't ride with you, your neighbors will hate you and you'll look and sound like a clown driving an otherwise awesome car. My 2 cents.

Rated 3 out of 5 by from Loud and Aggressive This is a quality product is excellent as you would expect but the sound clips do it too much justice in that it is much louder than expected, especially when cruising under load at low RPM. It drones very badly, so much so that it makes the door panel rattle. Great under throttle, but just not tolerable for cruising up a slight hill.

Rated 4 out of 5 by from Deep Rumble Okay so the part is awesome and install was only 40 minutes with a lift. It was actually a really easy install and I couldn't be happier with the install. The exhaust is really loud and deep. The rumble is awesome. I must say that the sound is a bit too loud for my neighbors and borderline for me. Drone is there at the 2k mark and it's rough. I still love it although I plan to add resonators to kill the drone. This is the deepest system I have heard and after going to cars and coffee last year nothing comes close in deepness.

Rated 5 out of 5 by from Throaty! Very easy install on my GT w/PP. Good quality kit. The exterior sound clips from CJ are pretty accurate. Deep mellow rumble below 2K both inside the car and out. If driven below 2K in 6th and lugging it there is significant drone, I don't mind it however I can understand how it might drive some people nuts. Can always downshift to 5th!

Rated 5 out of 5 by from Just as a real muscle car should sound... Yes, it is loud and aggressive, but isn't is suppose to be? I like it. It's what it should sound like. If you don't like a drone, if you don't like loud and aggressive, then it's not for you. I want something load enough to turn heads and this is it.

Rated 5 out of 5 by from What a great sounding exhaust system. 60's again. If you want muscle car sound, this is for you. Can't stop smiling.

MagnaFlow Cat-Back Exhaust Kit Competition Series 3" Stainless Steel GT 2015-2017 Video Transcript
By Bill Tumas: One of the first modifications most Mustangers do to their car is a new exhaust system. We don't expect the 2015 owners are going to be any different. While the factory system doesn't sound bad, it's kind of on the restrictive side. Inside the car, you can barely hear it. Today we're going to remove our factory exhaust system and replace it with this Competition cat-back from MagnaFlow.

The Competition cat-back from MagnaFlow is going to be a bolt-on exhaust. It requires no cutting to install. It's a full three-inch system made of stainless steel. It uses an X plate, leading through a set of straight-through style mufflers, with a set of four-inch polished tips. This system is designed to be aggressive sounding, give your Mustang a really unique sound.

Before we begin the installation, we'll start off with some sound clips of the factory exhaust. (car exhaust sounds) Not bad for a stock system, but we can definitely do better.

For this installation, we need a lift or a jack and jack stands, 3-inch ratchet, 13-millimeter deep socket, 15-millimeter deep socket, 6-inch extension, and safety glasses.

We're going to start by giving you an overview of the factory exhaust system on the '15 before we install our cat back. Starting off here, we have our factory catalytic converters, look similar to previous years, the difference being here, on the driver's side, the catalytic converter and header is all one piece. They make it unique to add an off-road system, but there will definitely be ways to do it in the future.

Back here, this is where our cat back is actually going to install. That's a good thing, because it gets rid of this. This is a large resonator. It's definitely going to produce, slow down the flow of the exhaust, kill the sound. It has a lot to do with the weight of the exhaust system, as well. Finally, we go back to a set of tailpipes which now go under the axle, because we have an IRS instead of a solid axle, and a set of standard-looking Ford mufflers.

We'll begin the cat back installation by removing the two sleeves that hold our factory cat back to our factory H-pipe. I'll just pull this tab out here, and we'll slide the clamp back. Once the clamps are loose, screw in the hangers for the tailpipes.

For the next step, you want a little bit of help. The last two hangers are located here for the mufflers. The whole exhaust system, though, will have to actually slide back to get off the H-pipe, and then go forward to get off the hangers. You'll definitely want an extra set of hands, because the whole exhaust is welded and it's quite heavy.

You'll need to get four pieces off the factory cat back we're going to use for our new installation. First is the sleeves up here. You also need both factory rear hangers.

We'll start the installation of our MagnaFlow cat back by reinstalling the factory sleeves on the H-pipe. Get them over the factory studs, then grab your MagnaFlow X. Put the X-pipe up into place. Now we're just going to snug these up. You don't want to tighten them all the way. Just get them tight enough so the X-pipe doesn't move.

Now we'll start with the tailpipes. You want to put a clamp on it first. Then reinstall the factory hanger, making sure the hook is facing towards the front of the car. Now we'll snug the clamp up. This one you want real tight at all, because you will have to twist the tailpipe to get the muffler aligned properly. Just snug it up so it doesn't move.

Once you have the tailpipes in place, reinstall the bolts on the factory hangers. That's the last clamp on the muffler. You want to leave them loose enough so you can bend it into place. Get the tip where you want it, and tighten down.

And your installation's finished. Now the part I was waiting for. Let's see how it sounds. (car exhaust sounds)

Now we'll take it for a drive with our MagnaFlow Competition on it. First thing you notice when you start the engine, the MagnaFlow's got a real deep tone, so you'll really feel it inside the car.

Our MagnaFlow Competition series cat back fit the car great, it looks great, but best of all it gave us that aggressive MagnaFlow tone we've come to know and love on all their systems. Installation's pretty straightforward, probably only take you around an hour. You'll be back on the road in no time.
