    Hey, everybody. Justin with AmericanMuscle.com, here with my complete breakdown of the Magnaflow Competition Series Catback Exhaust System fitting your 2015 Coyote powered GT. Magnaflow has definitely made a name for themselves over the past 30 or so years, as one of the best in the biz, thanks largely in part to their quality build, great sound and perfect fitment. The Competition Catback from Magnaflow will no doubt be one of the more aggressive systems available for your Coyote Powered GT, and will certainly be much more aggressive when compared to the Magnaflow Street Catback. The main difference in sound is simple; it's in the muffler here. This is a straight-through design which will not only free up a lot of power, but also give you that very tough sound a lot of us Mustang owners are after. Getting into some of the specifics, you will notice the competition includes 3-inch mandrel bent tubing from the included crossover, or X pipe, which does take the place of that factory suitcase portion of your exhaust, along with these straight-through competition mufflers and out the brightly polished, rather large, four-and-a-half inch tips. I do want to point out that this entire kit has been constructed from 100% quality stainless steel. So besides looking good for years to come, you're also going to save a few pounds when compared to your factory, rather hefty, exhaust there. Now guys, if you do want to see more detailed photos of this exhaust including some customer reviews, then just click on the link below to head back to the product page, if you're not already there. Since the 2015s are equipped with IRS, removing the old exhaust and bolting up the new Catback should be a lot easier than previous generations, thanks largely in part that you don't have to deal with those over-axle pipes. With that being said, removing that factory exhaust and installing the new Competition here from Magnaflow, should only take you about two hours using basic hand tools. Now it's time to hear how the Magnaflow Competition Catback sounds compared to our factory exhaust.

    Add Horsepower. Stop choking off your high powered 5.0L V8 with a stock exhaust system and enjoy more horsepower with a Magnaflow Competition Cat-Back. By reducing back pressure and giving your GT Mustang a free-flowing exhaust, you'll see great power and torque gains.

    Aggressive Muscle Car Sound. Give your coyote powered 2015-2017 GT Fastback the deep, aggressive rumble it deserves with a Magnaflow Competition Cat-Back. This premium quality exhaust features free-flowing, straight-through mufflers that increase power and give your GT an unmistakable muscle car sound.

    Magnaflow Quality. Constructed from durable 3" diameter mandrel bent stainless steel tubing for it's corrosion resistant properties, this Magnaflow Cat-Back features two straight-through mufflers with black powder coated 4.5" stainless tips, that exit in the stock locations for impressive muscle car looks and sound.

    Application. Made to be a direct bolt on, this Magnaflow Competition Cat-Back Exhaust with black tips will bolt straight up to the factory Mid-Pipe without any extra modifications required on the 2015-2017 GT Mustang to give it the deepest, most aggressive sound possible. This Magnaflow Competition Cat-Back Exhaust fits both the fastback and convertible models.

        Will these need a difference length mid pipe to bolt up to long tube headers?

        • The Magnaflow Competition Cat-Back Exhaust is specifically designed to bolt to the factory mid-pipe. We cannot guarantee what would be needed to bolt up to long tube headers correctly.

        Will these hook right up to a Stainless 1 7/8 Longtube header?

        • The Magnaflow Competition Cat-Back Exhaust is made to be a direct bolt on to the factory mid-pipe.

        Helpful (0)

        What type of long tube headers are compatible with this exhaust?

        • With the Magnaflow Competition Cat-Back Exhaust I would recommend purchasing the Borla 1-3/4 in. Long Tube Off-Road Headers, these would be a direct fit and would also fit your factory exhaust if you purchased an additional piece.

            Nice deep tones. Not extremely loud. Very good all around, but maybe too expensive for what you get

            Drooone!!!

            After watching a lot of videos about Magnaflow Competition Cat-Backs to listen to the sound and reading reviews about the system I was excited to buy it. However, after installing the Competition onto my 17 Mustang GT I found out just how bad the drone is. Due to me not owning any lift to hoist my car up to install I had to drive 80 miles to my fathers to install only to drive another hour and a half home with this horrendous drone and had to pop a few Advil to get rid of my headache.

            I can not discribe with words from the English language the size and purity of the smile I had the first time I started my car up after installing these. Yes, it is loud. Yes there is some cabin drone. Yes they are worth EVERY PENNY!!!

            Deep rumble

            If you have listen to the sound clips, they do not do it justice. This exhaust system is perfect for anyone that wants that true muscle car sound. It sends those ricers running for the hills. Also you can't go wrong with black tips, they give the back your car that complete look!

            Amazing sound

            So, I had these installed about two weeks after buying the car and they sound how a mustang should. I love the loudness and deep note however, I did get a little highway drone. Although this isn't my primary vehicle I found it pretty annoying. A little sound deadening material and all was perfect. I get a ton of compliments on the sound of this exhaust. Pull the trigger on this one. You won't regret it.

            Great Exhaust

            I have to give this exhaust 5 stars in every respect. Get more compliments on the tone and overall sound of this product. When I had a supercharger installed it was out of this world. It does have an agressive loud cold start sound, so firing it up at 5:00 am might upset the neighbors though.

            Moarrrrrr Roarrrrr

            Wow! These everything I wanted in an exhaust sound. Nice deep rumble at low RPM and then she rasps, barks and howls at the moon after that. Clean install. Like the nice look of the black streamlined cylinder before the tip. This was a huge selling factor for me as I didn't want the huge silver muffler can under the rear bumper like with Corsas.

            What a difference!

            Never have a seen a exhaust system fit so well. I wish the instructions told about the slightly larger side of the X pipe. It does go on the passenger side. But over the sound is great the install was easy and it looks great!

            Super easy installation and a must have to your mustang GT. Would suggest using 2 people because stock exhaust is relatively bulky and heavy. Took about an hour to install. Definitely frees up some hp while reducing some weight on your car.
