Review & Install Video

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.

  • The Magnaflow Competition Cat-Back Exhaust installs after emissions control equipment, so this will have no issues with smog testing. We recommend checking local noise regulations to ensure this exhaust will not violate local vehicle noise regulations.

    I literally can't find anything wrong with it

    If you are looking for an exhaust to turn some heads, this is the exhaust to go for! I had the luxury of hearing the Ford Racing Borla exhaust (a friend decided to get those), and I liked them don't get wrong. I could just tell from the video though that Magnaflow provided a deeper sound. I went for it and couldn't be happier. I read multiple reviews from multiple sites, and droning seemed to be possible, however, I do not have any whatsoever, but I know it can still be possible. Took about an hour to install with the right equipment, and thats counting taking off the stock exhaust. If you are inexperienced with putting on an exhaust, it can take a couple of hours. Bottom line for me: If you like a growl sound, go with the Borla, but if you like a rumble, go with the Magnaflow!

    Magnaflow comp cat back

    I chose to go with the magnaflow comp over the Borla touring (the 2 exhausts I debated on purchasing) simply for one reason... The much deeper tone Magnaflow is well known for. To be honest I did not care so much for being "loud" but I wanted that overall deeper tone. And well the extras (4" black tips, 3" exhaust piping) helped with the decision process. Install: to be honest it would have taken me about an hour using jack and jack stands however I was an idiot and put the X pipe on wrong assuming the longer pipe went on the passenger side rather than the driver side (why... I don't know? Instructions were vague stating just to install, pipe is not marked, and the video on YouTube didn't mention anything about it) so it took me roughly an hour and half to complete. And I needed my buddies only help to remove the stock exhaust because it's one large awkward welded piece. Product: All the parts went together smoothly. The finish on the black tips was more of a flat black rather than a gloss black which went well with the black trim around the vehicle. The exhaust was well packaged and wrapped to ensure no dents/scratches. Sound: I took my own before and after video to see/feel the difference. Well it was a waste of time because once I started the car, after installing the new exhaust, it was an immediate upgrade in sound quality. It was a complete sound makeover for the mustang. I could feel the deep rumble as a faint vibration in the drivers seat. The sound is exactly what I wanted! I wanted to stay away from the higher pitched type of exhaust and I hate the "empty exhaust can" sound. I must say I dont regret going with Magnaflow competition. If anything the sound is too loud rather than not loud enough.

    Magnaflow Competition Exhaust

    Installed the Magnaflow Competition Catback in under an hour. The fit was perfect. As a service manager for a Ford dealership, I have seen many different system that didn't fit well. The 3" pipes seem possibly a little large seemed to leave a small flat spot on the bottom end when launching the car hard. The car also has a Jack Roush intake system and a Roush tune. The sound is incredible actually had someone follow me home the following day when they hear the car go by. Very happy with the purchase and would highly recommend this product.

    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!

    awesome sound!!

    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.

    Magnaflow Comp. cat-back exhaust

    Like the black tips very much. Louder than I thought it would be. Recordings don't really reflect the sound in the car. Definitely gets noticed more than before install. Fit was good except getting the tips to look perfect took some bending of the brackets.
